An image capturing optical lens system includes, 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. The first lens element with positive refractive power has a convex object-side surface. The second lens element has negative refractive power. The third lens element with positive refractive power has a convex image-side surface. The fourth lens element with refractive power has a concave object-side surface and a convex image-side surface. The fifth lens element with refractive power is made of plastic material, and has a concave image-side surface, wherein the fifth lens element has at least one inflection point formed on at least one of the surfaces thereof. The surfaces of the third lens element, fourth lens element and fifth lens element are aspheric.
