PURPOSE:To eliminate the possibility of the generation of scorching by forming an interference film for compensating sensitivity onto the surface of a birefringent plate and bonding the birefringent plate with the front surface of a solid-state image pickup element. CONSTITUTION:An interference film 12 for compensating sensitivity is shaped previously onto the surface of a birefringent plate 11, and the birefringent plate 11 is fixed onto the front surface of a solid-state image pickup element 10 through proper dhesives. Since the birefringent plate, the surface thereof is coated with the interference film for compensating sensitivity, is bonded directly with the solid-state image pickup element, a filter for compensating sensitivity which have been used positively can be omitted, thus compacting the constitution of the element, then also reducing weight. Since a birefringent plate made of quartz has strong melting resistance to the outside air, no scorching is generated even when the birefringent plate and the solid-state image pickup element are not bonded sufficiently. |
