PROBLEM TO BE SOLVED: To provide a bidirectional optical transceiver module which is made small-sized. SOLUTION: The bidirectional optical transceiver module includes a photodetecting element which is installed on a printed board through a chip-on-board process and receives a 1st optical signal and a light source which is installed by To-can packaging and transmits a 2nd optical signal. Or the bidirectional optical transceiver module includes the photodetecting element which is installed on the printed board through a chip-on-board process and receives the 1st optical signal and the light source which is installed through a chip-on-board process and transmits the 2nd optical signal.
