PURPOSE:To obtain an optical receiver having an excellent performance by fixing an optical fiber by a supporting body which has been brought to bending to a prescribed shape, in a light receiving element. CONSTITUTION:In a supporting body 8 which has been brought to bending to a prescribed shape, an optical fiber 5 is inserted and fixed, and it is fixed to a photodetector in a connecting part 4. The optical fiber 5 is inserted into the supporting body 8 consisting of a copper pipe, and thereafter, the supporting body is brought to bending, and it is aligned and fixed by using a usual fine motion base so that the light receiving sensitivity becomes maximum, to a light receiving part of an InGaAs PIN photodiode. In this state, the sensitivity being equal to the sensitivity when a conventional light receiving element with an optical fiber has been used linearly is obtained.
