1. A photographing optical lens assembly comprising five lens elements, the five 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 and a fifth lens element; each of the five lens elements having an object-side surface facing towards the object side and an image-side surface facing towards the image side;
wherein the first lens element has positive refractive power, the object-side surface of the first lens element is convex in a paraxial region thereof;
the object-side surface of the second lens element is convex in a paraxial region thereof;
the third lens element has negative refractive power;
the object-side surface of the fourth lens element is concave in a paraxial region thereof, both of the object-side surface and the image-side surface of the fourth lens element are aspheric;
wherein a total number of lens elements in the photographing optical lens assembly is five; a central thickness of the first lens element is a maximum among central thicknesses of the five lens elements; an axial distance between the third lens element and the fourth lens element is a maximum among axial distances between every adjacent lens elements of the five lens elements; an absolute value of a curvature radius of the object-side surface of the fifth lens element is larger than an absolute value of a curvature radius of the object-side surface of the second lens element;
