1. A photographing optical lens assembly comprising seven lens elements, and 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;
wherein the second lens element has an object-side surface being convex in a paraxial region thereof, an image-side surface of the sixth lens element has at least one inflection point, a curvature radius of an object-side surface of the first lens element has a same sign as a curvature radius of an image-side surface of the third lens element, and an absolute value of a curvature radius of an image-side surface of the fourth lens element is larger than an absolute value of a curvature radius of an object-side surface of the fifth lens element;
wherein a curvature radius of an object-side surface of the sixth lens element is R11, a curvature radius of the image-side surface of the sixth lens element is R12, a curvature radius of an image-side surface of the seventh lens element is R14, a focal length of the photographing optical lens assembly is f, and the following conditions are satisfied:
−2.0<(R11−R12)/(R11+R12)<0.2; and
0<R14/f<0.7.
