A compound-eye imaging device comprises: an optical lens array with integrated optical lenses; a stop member for shielding unnecessary ambient light from entering the optical lens array; a photodetector array placed at a predetermined distance from the optical lens array for imaging images formed by the optical lenses; and a light shielding block placed between the two arrays for partitioning a space between the two arrays into a matrix of spaces as seen on a plane perpendicular to the optical axis of each optical lens to prevent lights from the optical lenses from interfering each other. The optical lenses are formed of a molded glass having a refractive index distribution to increase the refractive index of each optical lens in the direction of light propagation. The focal length of each optical lens can be reduced as compared with an ordinary lens, thereby reducing the thickness of the compound-eye imaging device.
