The present invention relates to an image pickup device, etc., having a structure such that electrostatic discharge is unlikely to occur when an FOP and a CCD reading part are joined. This image pickup device comprises a semiconductor substrate, provided with the CCD reading part on a front surface that opposes a back surface, which serves as a light-incident surface, a package having a cavity in which the semiconductor substrate is fixed, a cover covering an upper opening of the cavity, an FOP joined to the semiconductor substrate, and electrical wirings. The cover has a guiding opening for inserting the FOP into the cavity, and the semiconductor substrate is thinned at a portion corresponding to a region at which the CCD reading part is disposed. Also, the semiconductor substrate is fixed to a bottom surface of the cavity such that the CCD reading part and the bottom surface face each other, and a light outgoing end surface of the FOP is optically coupled to the thin part of the semiconductor substrate in the state of being inserted into the cavity from the guiding opening.
