Patent ID: 8466409

Claim:
A photoelectric conversion module, comprising: a transmission side photoelectric conversion part for converting an electrical signal into an optical signal; a transmission side circuit board on which the transmission side photoelectric conversion part is mounted off-center to one side of the transmission side circuit board at one end of the transmission side circuit board; a reception side photoelectric conversion part for converting an optical signal into an electrical signal; and a reception side circuit board on which the reception side photoelectric conversion part is mounted off-center to one side of the reception side circuit board at one end of the reception side circuit board, wherein a surface of the transmission side circuit board on which the transmission side photoelectric conversion part is mounted is opposite to a surface of the reception side circuit board on which the reception side photoelectric conversion part is mounted, the transmission side photoelectric conversion part and the reception side photoelectric conversion part are located between the transmission side circuit board and the reception side circuit board, and the transmission side photoelectric conversion part and the reception side photoelectric conversion part are arranged in parallel in a width direction of each circuit board.
