<p>PROBLEM TO BE SOLVED: To provide an optical transceiver module which can be downsized without deteriorating various properties. SOLUTION: In an optical transceiver module where a light emitting element on transmission side, a light receiving element on reception side, and a peripheral circuit are mounted, a part mounting board 20 which is constituted as one substrate out of a plurality of glass epoxy resin substrates 3a, 3b, 3c, and 3d and flexible structures 2 connected electrically to the inner layers of these resin substrates 3a, 3b, 3c, and 3d is stored in the casing 10, and the above resin substrates 3a, 3b, 3c, and 3d are arranged to correspond to the bottom walls 10a and 10b and upper wall 10d of the casing 10, in condition that the above part mounting substrate 20 is bent in the above flexible structure 2.</p> |
