Multiple semiconductor elements in a semiconductor module in which multiple spherical light receiving or emitting semiconductor elements are installed can easily be retrieved, reused, or repaired. In a semiconductor module 60, two segment modules 61 are serially arranged in a storage casing 62. The segment modules 61 are each formed by molding solar battery cells 10 arranged in a matrix of multiple rows and columns, and a conductive connection mechanism serially-connecting the solar battery cells 10 in each column and parallel-connecting the solar battery cells 10 in each row in a synthetic resin with connection conductors 67 protruding at the ends. Conductive corrugated springs 70 and external terminals 76 are provided at the ends of the storage casing 62. The mechanical pressing force of the conductive corrugated springs 70 ensures that the two segment modules 61 are serially connected.
