Claim 0:
1. A photographing optical lens assembly comprising six lens elements, the six 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 and a sixth lens element;
wherein each of the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element and the sixth lens element has an object-side surface facing towards the object side and an image-side surface facing towards the image side;
wherein the object-side surface of the first lens element is convex in a paraxial region thereof; the third lens element has positive refractive power, the object-side surface of the third lens element is convex in a paraxial region thereof, and the image-side surface of the third lens element is convex in a paraxial region thereof; the fourth lens element has positive refractive power; the fifth lens element has negative refractive power, and at least one of the object-side surface and the image-side surface of the fifth lens element is aspheric; the sixth lens element has positive refractive power, the object-side surface of the sixth lens element is convex in a paraxial region thereof, the image-side surface of the sixth lens element is concave in a paraxial region thereof, and the image-side surface of the sixth lens element is aspheric and comprises at least one inflection point; there is an air gap between each of adjacent lens elements of the six lens elements;
wherein a focal length of the photographing optical lens assembly is f, a focal length of the third lens element is f3, and the following condition is satisfied:

0.53≤|f/f3|.
