Claim Text:
1. A photographing optical lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof; a second lens element having positive refractive power; a third lens element; a fourth lens element; a fifth lens element with negative refractive power having an image-side surface being concave in a paraxial region thereof, wherein both of an object-side surface and the image-side surface of the fifth lens element are aspheric; and a sixth lens element having an image-side surface being concave in a paraxial region thereof, wherein both of an object-side surface and the image-side surface of the sixth lens element are aspheric, and the image-side surface of the sixth lens element has at least one inflection point; wherein the photographing optical lens assembly has a total of six lens elements, there is an air gap in a paraxial region between any two of the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element and the sixth lens element that are adjacent to each other, a focal length of the photographing optical lens assembly is f, a focal length of the second lens element is f2, a curvature radius of the image-side surface of the fifth lens element is R10, an axial distance between the object-side surface of the first lens element and an image plane is TL, a maximum image height of the photographing optical lens assembly is ImgH, and the following conditions are satisfied:
