PURPOSE:To reduce the size of a cooling type photoelectric converter by forming a polyhedron on the external circumferential surface of a cooling board on which a photoelectric converting element is arranged and dispersedly arranging elements for processing signals from the photoelectric converting element on respective surfaces of the polyhedron. CONSTITUTION:An airtight vessel having a Dewar construction is constituted by both inner and outer tubes 1, 2 and the space between these inner and outer tubes 1, 2 is kept under vacuum. A cooling board 24 is cooled by an electronic cooler 9 to cool an infrared-ray detecting element 25. The sides of the cooling board 24 are formed like a polyhedron and a signal processing element 26 for reading out and processing signal outputs from the infrared-ray detecting element 25 and a driving element 26' for driving the signal processing element 26 are arranged on each surface of the polyhedron. |
