An image lens assembly includes five lens elements which are, in order from an outer side to an inner side along an optical path: 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 has an outer-side surface facing toward the outer side and an inner-side surface facing toward the inner side. The outer-side surface of the first lens element is concave in a paraxial region thereof, and the outer-side surface of the first lens element has at least one inflection point.
