Claim Text:
1. A photographing optical lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof; a second lens element having refractive power; a third lens element having positive refractive power; a fourth lens element having refractive power; a fifth lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof, wherein both of the object-side surface and the image-side surface of the fifth lens element are aspheric; and a sixth lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, wherein both of the object-side surface and the image-side surface of the sixth lens element are aspheric, and the image-side surface of the sixth lens element has at least one inflection point; wherein the photographing optical lens assembly has a total of six lens elements with refractive power, a central thickness of the fifth lens element is CT5, a central thickness of the sixth lens element is CT6, 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, a focal length of the photographing optical lens assembly is f, a focal length of the first lens element is f1, a focal length of the fifth lens element is f5, a focal length of the sixth lens element is f6, and the following conditions are satisfied:
