A signal transmission device includes a transmission line. The transmission line is configured to receive a signal transmitted from a transmission device, and output the signal to a receiving device. The transmission line includes a signal suppression device. The signal suppression device is coupled to the receiving device, and is configured to suppress a reflection signal reflected from the receiving device. The signal suppression device includes a pull-up element and a compensation element. The pull-up element is configured to decrease an equivalent impedance from the signal suppression device to the receiving device. The compensation element is configured to compensate for the equivalent impedance from the signal suppression device to the receiving device. A first terminal of the pull-up element is coupled to a first terminal of the compensation element, and a second terminal of the compensation element is coupled to the receiving device.

In a communication apparatus, an analog circuit executes an analog process to a differential signal in a condition that a potential of a first conductor is a reference. A communication circuit receives, via a connection circuit, a differential signal obtained by the execution of the analog process of the analog process is executed and generates, based on the received differential signal, a signal with a reference corresponding to a potential of a second conductor. An inductor (a connection element) is connected between the first conductor and the second conductor. The connection circuit includes a circuit element other than a capacitor.
