1. A photographing optical 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, and 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 second lens element has positive refractive power, the object-side surface and the image-side surface of the seventh lens element are both aspheric, the image-side surface of the seventh lens element is concave in a paraxial region thereof, and the image-side surface of the seventh lens element has at least one convex shape in an off-axis region thereof;
wherein an Abbe number of the sixth lens element is V6, an f-number of the photographing optical lens assembly is Fno, and the following conditions are satisfied:
10<V6<32; and
Fno<2.0.
