An imaging optical lens assembly includes five optical elements with refractive power. The five optical elements, in order from an object side to an image side along an optical path, are a first optical element, a second optical element, a third optical element, a fourth optical element, and a fifth optical element. The first optical element has an object-side surface being concave in a paraxial region thereof. The third optical element has negative refractive power.
