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 has negative refractive power. The second lens element has an object-side surface being convex. The fourth lens element has an image-side surface being convex. The fifth lens element has negative refractive power. A total number of the lens elements in the image capturing optical lens assembly is five.
