Abstract
Provided is a stack-type lens array capable of preventing a lens from peeling off due to stress during dicing or vibration and impact when used. The stack-type lens array is formed by stacking and bonding two lens sheets in which micro lenses are arranged on a flat portion at predetermined intervals. Antireflection films are vapor-deposited on a convex surface and a concave surface of the lens and a light shielding film is vapor-deposited such that a circular opening is formed at the center of the concave surface. The opening serves as a diaphragm aperture of the lens. An exposed surface in which neither the antireflection film nor the light shielding film is vapor-deposited is provided outside the light shielding film between adjacent lenses. A dicing line is set at the center of the exposed surface. An adhesive layer is formed in a predetermined pattern on the exposed surface.
