Abstract: Ringing occurring in a digital signal to be transmitted, is reduced or suppressed. A transmission module Ma includes a transmitter 200a configured to transmit a digital signal, a transmission antenna 100a constituted by a metal plate, or by a conductor formed on an insulator. The transmission antenna 100a is configured to be electromagnetically or magnetically coupled to a reception antenna 100b of a non-contact reception module Mb for digital communication. A resistor 400a is connected in series between the transmitter 200a and the transmission antenna 100a.
