A compound-eye imaging device comprises: an optical lens array with integrated optical lenses; a stop member; a photodetector array for imaging multiple images formed by the optical lenses; and a light shielding block for partitioning a space between the two arrays into a matrix of spaces, with light-passing holes, so as to prevent lights emitted from the optical lenses from interfering each other. The light shielding block is formed of unit plates in a stack, each having light-passing windows. Each light-passing window has blackened surface. The unit plates in the stack are alternately reversed upside down and left-right so as to allow the horizontal positions of the light-passing windows for forming each light-passing hole through the unit plates in the stack to be alternately offset in depth direction of the hole, thereby forming an irregular inner wall surface which serves as a light scattering surface to prevent e.g. ghost.
