NOVELTY - The apparatus (1) has a lower electrode layer (10) arranged on a substrate. A compound semiconductor layer (13) of a chalcopyrite structure is designed such that the lower electrode layer is covered. A transparent electrode layer (4) is arranged on the semiconductor layer. The lower electrode layer is arranged in the transparent electrode layer. An electrode separated layer (5) is embedded along a region between mutually adjacent lower electrode layers in the transparent electrode layer, and consists of insulating material that separates the transparent electrode layer into the region.    USE - Photoelectric conversion apparatus e.g. solid-state image sensor such as line image sensor and area image sensor, for use on a solar cell for detecting light e.g. visible light and near infrared light, obtained from energy of light converted into an electric signal. Can also be used for a personal-identification camera, a security camera, a vehicle-mounted camera of a car for ensuring nighttime visual aid and distant visual field, a medical near-infrared light detection apparatus, a wide photon detection apparatus and an avalanche photo-diode.    ADVANTAGE - The apparatus allows a contact surface of the compound semiconductor layer that is in contact with the transparent electrode layer through a buffer layer to be separable into different areas at pixel cells, so that a depletion layer can be extended independently to a pixel cell set in the compound semiconductor layer and pixel separation of the compound semiconductor layer can be electrically carried out, thus reducing crosstalk of the apparatus, preventing generation of interface state defects in an end surface of the compound semiconductor layer and minimizing dark current of the apparatus, and hence improving yield of the apparatus.    DETAILED DESCRIPTION - The insulating material is selected from a group consisting of silica and black resin. An INDEPENDENT CLAIM is also included for a photoelectric conversion apparatus manufacturing method.
