An image capturing optical lens assembly 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 object-side surface and a concave image-side surface. The fourth lens element with positive refractive power is made of plastic material, and 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 convex image-side surface. At least one of the object-side surface and the image-side surface of the third lens element, the fourth lens element and the fifth lens element are aspheric.
