In a transmission device having a first transmission path which is provided on a first printed circuit board and is connected to a connector, and over which a signal which does not vary with time is transmitted, and a second transmission path which is provided on a second printed circuit board and is connected to a second connector, and over which the above-mentioned signal is transmitted, a first resistor is connected to couple the second transmission path with a power supply of the second printed circuit board, and a first capacitor connected to couple the second transmission path with the ground. The first transmission path may also be grounded via a capacitor. The capacitive coupling to the ground will effectively ground the transmission path, and the crosstalk from another transmission path over which a signal which varies with time is transmitted is reduced.
