| Zusammenfassung: | An image pickup device according to the present invention comprises (1) a fiber optical plate constituted by bundling a plurality of optical fibers, including a core and a cladding covering an outer periphery thereof and having a light incident surface and a light-emitting surface inclined with respect to the optical axis direction of a plurality of optical fibers; (2) a plurality of columnar crystals having light permeability, formed on the light-emitting surface of the fiber optical plate; and (3) a solid-state image pickup device having photoelectric converters arrayed and formed in two-dimensional fashion on a main surface of a semiconductor substrate and optically coupled to a plurality of columnar crystals. |
