摘要
[Object] The invention reduces or suppresses ringing occurring in a digital signal to be transmitted.;[Configuration] 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 being configured to be electromagnetically or magnetically coupled to a reception antenna 100b of a non-contact reception module Mb for digital communication, and a resistor 400a connected in series between the transmitter 200a and the transmission antenna 100a. The resistor 400a has such a resistance value that the resistor 400a entirely blunts a waveform of the digital signal outputted from the transmitter 200a so as to reduce or suppress ringing occurring in the digital signal. The blunted digital signal is to be inputted into the transmission antenna 100a.
