PROBLEM TO BE SOLVED: To prevent ultraviolet rays for hardening a sealing agent from entering a light receiving surface and deteriorating characteristics of a solid-state imaging element, and also to prevent the intrusion of a flowed-out sealing agent into the light receiving surface by uniformly irradiating the ultraviolet rays on a portion which needs be irradiated with the ultravilet rays. SOLUTION: Between a package 4 and the emission end 12 of an optical fiber 11, a metallic lightproof mask 10 is formed. In the lightproof mask 10, a plurality of through holes 15 are formed to allow ultraviolet rays to pass through only necessary parts and then incident into the package 4. By changing sizes of the through holes 15 according as the ultraviolet rays are irradiated, a variation in illuminance can be eliminated. COPYRIGHT: (C)2006,JPO&NCIPI
