Claim:
1. A photographing optical lens assembly comprising, in order from an object side to an image side: a first lens element; a second lens element, both of an object-side surface and an image-side surface of the second lens element being aspheric; a third lens element, both of an object-side surface and an image-side surface of the third lens element being aspheric; a fourth lens element having negative refractive power, both of an object-side surface and an image-side surface of the fourth lens element being aspheric; and a fifth lens element having an image-side surface being concave in a paraxial region thereof, at least one inflection point on the image-side surface, and both of an object-side surface and the image-side surface of the fifth lens element being aspheric; wherein the photographing optical lens assembly has a total of five lens elements, a curvature radius of an object-side surface of the first lens element is R1, a curvature radius of an image-side surface of the first lens element is R2, an axial distance between the object-side surface of the first lens element and an image surface is TL, a maximum image height of the photographing optical lens assembly is ImgH, and the following conditions are satisfied:
