Disclosed is a microphone that can be highly integrated and can be manufactured easily. A light emission element and a light-receiving element mounted on a substrate are sealed with transparent resin, a groove is formed in the sealed portion between the light emission element and the light-receiving element, an optically non-transparent substance is inserted in the groove, and the optically non-transparent substance is adhered to the groove with transparent resin. Thereby, in comparison to the conventional method of cutting the sealed portion together with the substrate, forming an optically non-transparent film on the cut surface, and reintegrating the cut areas, with the present invention, the number of the alignment processes is reduced and the extra margin for the setting process is no longer unnecessary. <IMAGE> |
