Claim Text:
1. A photographing optical lens assembly consisting essentially of five lens elements, in order from an object side to an image side: a first lens element having an object-side surface being concave in a paraxial region thereof; a second lens element; a third lens element; 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 and at least one inflection point, both of an object-side surface and the image-side surface of the fifth lens element being aspheric; wherein an axial distance between the first lens element and the second lens element is shorter than an axial distance between the second lens element and the third lens element, a curvature radius of the image-side surface of the fifth lens element is R10, a focal length of the fourth lens element is f4, 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:
