PURPOSE:To prevent deterioration in the characteristic of a picture by coating the side surface of an optical-fiber bundle adhered to the image pickup plane of a solid-state image pickup element with a transparent resin, with a light- absorbing material or light-shielding material. CONSTITUTION:An image formed on the photoelectric plane 2a of an image intensifier 2a lens 1, optically amplified and outputted to a fluorescent plane 2b, and further, transmitted through the optical fiber bundle 5 and made incident to the image pickup plane 4a of the solid-state image pickup element 4. Then the element 4 executes photoelectric conversion and outputs the result as an electric signal. On the surface of the bundle 5, a light-shielding chromium is vapor-deposited. An external light is shielded by the said chromium 7 and c an not enter the bundle 7 from its side surface. Therefore, the occurrence of noise is prevented, hence the characteristic of a picture does not deteriorate.
