Abstract
A non-contact rotating coupler for transmitting a signal through coupling capacitances formed between opposite coupling plates arranged apart from each other. In the coupling plate, an inductance for causing a parallel resonance in a signal frequency band with a stray capacity existing between a grounded conductor and a non-grounded conductor is connected between a junction point of a resistor and a capacitor and the grounded conductor or between the non-grounded conductor and the grounded conductor, thereby reducing a coupling loss.
