An aspherical type imaging lens array comprises, from object side to image side, at least an aperture, a first positive meniscus lens with a convex surface facing the object side, a second meniscus lens with a convex surface facing the image side, and a third lens meniscus lens with a convex surface facing the object side. The respective lenses are made of plastic and has two aspherical surfaces, a focal length of the aspherical type imaging lens array is f, a focal length of the second lens is f2, and a focal length of the third lens is f3, they satisfy the equation: -0.20
