Abstract: An imaging optical lens assembly includes four lens elements which are, in order from an object side to an image side: a first lens element, a second lens element, a third lens element and a fourth lens element. Each of the four lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. At least one of all lens surfaces of the four lens elements is aspheric and has at least one inflection point.
