Claim:
1. A photographing optical lens assembly comprising, in order from an object side to an image side: a first lens element having positive refractive power; a second lens element having positive refractive power; a third lens element; a fourth lens element having positive refractive power; a fifth lens element having negative refractive power; and a sixth lens element having an image-side surface being concave in a paraxial region thereof, wherein the image-side surface of the sixth lens element has at least one convex shape in an off-axis region thereof, and both of an object-side surface and the image-side surface of the sixth lens element are aspheric; wherein the photographing optical lens assembly has a total of six lens elements, both of an absolute value of a focal length of the fourth lens element and an absolute value of a focal length of the fifth lens element are smaller than an absolute value of a focal length of the first lens element, an absolute value of a focal length of the second lens element, an absolute value of a focal length of the third lens element and an absolute value of a focal length of the sixth lens element, the focal length of the first lens element is f1, the focal length of the second lens element is f2, and the following condition is satisfied:
