Claim 15:
16. A photographing lens assembly comprising seven lens elements, the seven lens elements being, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element; each of the seven lens elements having an object-side surface facing toward the object side and an image-side surface facing toward the image side;
wherein the object-side surface of the seventh lens element is convex in a paraxial region thereof, and the image-side surface of the seventh lens element is concave in a paraxial region thereof and has at least one convex shape in an off-axis region thereof;
wherein an Abbe number of the third lens element is V3, an Abbe number of the fifth lens element is V5, an Abbe number of the sixth lens element is V6, a minimum value among Abbe numbers of the seven lens elements of the photographing lens assembly is Vmin, an axial distance between the object-side surface of the first lens element and an image surface is TL, an axial distance between the sixth lens element and the seventh lens element is T67, and the following conditions are satisfied:

30.0<V3+V5+V6<90.0;

Vmin<21.5; and

2.0<TL/T67<12.0.
