A photographing optical lens assembly includes, in order from an object side to an image side: the first lens element with positive refractive power having a convex object-side surface, the second lens element with positive refractive power, the third lens element with positive refractive power, and the fourth lens element with positive refractive power. By such arrangement, the total track length of the photographing optical lens assembly would be suitable for compact electronics.
