Claim 6:
7. A non-contact transmission method comprising: applying a digital signal to at least one resistor having a resistance value and thereby entirely attenuating, over the entire frequency range, frequency components of the digital signal so as to reduce or suppress ringing occurring in the digital signal, wherein the at least one resistor is connected in series to a transmission antenna and the transmission antenna is configured to be electromagnetically or magnetically coupled to a reception antenna of a non-contact reception module; and inputting the digital signal, with the frequency components thereof attenuated over the entire frequency range, directly into the transmission antenna from the at least one resistor, wherein the resistance value of the at least one resistor is between several ohms and hundreds of ohms, the applying of the digital signal includes applying the digital signal, which has been transmitted from a transmitter and contains high frequency components of a plurality of hundred MHz or higher, to the at least one resistor, and a distance between the transmitter and the transmission antenna is between a plurality of millimeters and 200 millimeters.
