A differential signal transmitting apparatus for transmitting a differential signal through two transmission lines. The apparatus includes: transmitting-side board connecting terminals 7a and 7b that are provided for each of the transmission lines 5a and 5b, and are able to connect a transmitting circuit 1 for transmitting a differential signal; receiving circuit connecting terminals that are provided at a far end of a daisy-chain connection extending from the transmitting-side board connecting terminals 7a and 7b provided for each of the transmission lines 5a and 5b, and connect the receiving circuit 2 for receiving the differential signal; and an undefined-logic preventing circuit 31 that is connected at a near end of the daisy-chain connection and outputs a prescribed potential difference to the receiving circuit connecting terminals when the transmitting circuit 1 is not connected to the transmitting circuit connecting terminals 7a, 7b. |
