     DETAILED DESCRIPTION 
     The present disclosure provides an imaging lens assembly which has an optical axis and includes at least one lens element. The lens element includes an optical effective region and a peripheral portion. The optical axis passes through the optical effective region. The peripheral portion surrounds the optical effective region and includes an object-side surface, an image-side surface, a peripheral surface, an annular marking structure and at least one arc portion. The object-side surface faces towards an object side. The image-side surface faces towards an image side and corresponds to the object-side surface. The peripheral surface connects the object-side surface and the image-side surface. The annular marking structure is disposed on one of the object-side surface and the image-side surface, and the annular marking structure is an annular tip-ended protruding structure and surrounds the optical axis. The arc portion is disposed on the other one of the object-side surface and the image-side surface, and the arc portion is an annular protruding arc. When a perpendicular distance between the annular marking structure and the optical axis is dm, a perpendicular distance between the arc portion and the optical axis is da, and a curvature radius of the arc portion is Ra, the following conditions are satisfied: 0.82&lt;da/dm&lt;1.18; and 0.025 mm≤Ra≤0.5 mm. 
     By disposing the annular marking structure only on one surface of the lens element and disposing the arc portion on the other surface, reflection of unnecessary light in the lens element can be reduced while the possibility of over reflection of unnecessary light can be prevented from disposing the annular marking structure on both of the object-side surface and the image-side surface of the lens element. Hence, by disposing the annular marking structure on the single side of the lens element and the arc portion on the other side thereof, size accuracy and demolding yield rate of the lens element can be improved. 
     Moreover, the annular marking structure can be for positioning the lens element so as to provide a function of compensating tolerance of production. 
     Specifically, the annular marking structure can be disposed on the image-side surface, and the arc portion is disposed on the object-side surface. The annular marking structure can be a step difference formed during demolding from a mold, a whole circular ring, or a ring with cutting edges, but the present disclosure is not limited thereto. Furthermore, a cross section of the annular marking structure can have an acute angle, wherein the acute angle is between 80 degrees and 100 degrees. In the embodiments, the acute angle is 90 degrees, but the present disclosure is not limited thereto. Moreover, the annular marking structure is an annular tip-ended protruding structure which has a sharped end. Specifically, a curvature radius of the end of the annular marking structure (Rm) can be less than 0.025 mm. 
     The lens element can be formed by injection molding and further include at least one gate trace, wherein the gate trace is disposed on the peripheral surface. Hence, the precision lens element with high accuracy and compactness can be provided. 
     When a distance from the annular marking structure to the gate trace along a direction perpendicular to the optical axis is t, the following condition can be satisfied: t≤0.4 mm. Hence, the efficiency of manufacturing during mass production process can be improved. 
     When the curvature radius of the arc portion is Ra, the following condition can be satisfied: 0.035 mm≤Ra≤0.45 mm. Hence, the possibility of adhesion between the lens element and the mold can be decreased, and it is favorable for quality management during demolding process. 
     When the perpendicular distance between the annular marking structure and the optical axis is dm, and a maximum radius of the peripheral surface is ds, the following condition can be satisfied: 0.7&lt;dm/ds&lt;1.0. Moreover, the following condition can be satisfied: 0.8&lt;dm/ds&lt;1.0. Hence, the coaxiality of two sides of the optical effective region can be improved. 
     The optical effective region can include an object-side optical surface and an image-side optical surface. The object-side optical surface faces towards the object side, the image-side optical surface faces towards the image side, and at least one of the object-side optical surface and the image-side optical surface is an optical aspheric surface. Hence, the lens element with high image resolution can be provided. 
     When a protruding height of the annular marking structure is h, the following condition can be satisfied: 0.0025 mm≤h≤0.1 mm. Hence, it is favorable for recognition by an instrument, and feasibility of demolding from the mold can be provided. 
     The present disclosure provides an imaging lens assembly module which includes a lens barrel and an imaging lens assembly. The lens barrel has a plurality of inner surfaces and forms an inner space. The imaging lens assembly is disposed in the inner space of the lens barrel. The imaging lens assembly has an optical axis and includes at least one lens element. The lens element includes an optical effective region and a peripheral portion. The optical axis passes through the optical effective region. The peripheral portion surrounds the optical effective region and includes an object-side surface, an image-side surface, a peripheral surface, an annular marking structure and at least one arc portion. The object-side surface faces towards an object side. The image-side surface faces towards an image side and corresponds to the object-side surface. The peripheral surface connects the object-side surface and the image-side surface and contacts one of the inner surfaces of the lens barrel physically. The annular marking structure is only disposed on the image-side surface, and the annular marking structure is an annular tip-ended protruding structure and surrounds the optical axis. The arc portion is disposed on the object-side surface, and the arc portion is an annular protruding arc. When a perpendicular distance between the annular marking structure and the optical axis is dm, a perpendicular distance between the arc portion and the optical axis is da, and a curvature radius of the arc portion is Ra, the following conditions are satisfied: 0.75&lt;da/dm&lt;1.25; and 0.025 mm≤Ra≤0.5 mm. 
     Hence, by disposing the annular marking structure on the image-side surface to improve the size accuracy of the lens element and disposing the arc portion on the object-side surface, demolding yield rate of the lens element can be improved. 
     Moreover, the annular marking structure can be for positioning the lens element so as to provide a function of compensating tolerance of production. 
     The object-side surface of the lens element can include an axial aligning structure for abutting against and aligning at center of an adjacent lens element. Hence, the yield rate of assembling can be improved so as to provide better image quality. Specifically, the axial aligning structure can include a tilt surface and a flat surface, and the tilt surface and the flat surface are for reducing tilting and shifting between the lens elements so as to align at center. 
     The image-side surface of the lens element can include an axial aligning structure for abutting against and aligning at center of an adjacent lens element. Hence, the yield rate of assembling can be improved so as to provide better image quality. 
     When a length of a region which the peripheral surface contacts the one of the inner surfaces along a direction parallel to the optical axis is L, the following condition can be satisfied: L&lt;0.1 mm. Hence, the possibility of generation of stray light can be decreased. 
     When the perpendicular distance between the annular marking structure and the optical axis is dm, and a maximum radius of the image-side optical surface is di, the following condition can be satisfied: 0.3&lt;di/dm&lt;0.8. Hence, the replacement rate of the mold can be reduced so as to reduce manufacturing cost.
