Abstract

PURPOSE:To improve S/N by preventing a leakage light to prevent the noise output dependent upon the leakage light by providing a light shielding film in a leakage light incident part through an insulating film. CONSTITUTION:Electrode 5 having prescribed light receiving window 6 is formed on the diode where P-type diffusion layer 2 is formed on N-type Si substrate 1, and is separated for every diode near the charge dam forming part upper face between diodes. Here, light shielding film 11 is provided in the leakage light incident part through insulating film 10. As a result, the leakage light is prevented to prevent the noise output dependent upon the leakage light, so that S/N can be improved.
