PROBLEM TO BE SOLVED: To perform simultaneous transmission by radio between a pair of adjacent couplers in a space saving manner. SOLUTION: The coupler includes a first conductive pattern provided on an insulating substrate and a second conductive pattern provided on the substrate and disposed facing the first conductive pattern. Also, the coupler includes a third conductive pattern provided on the substrate and a fourth conductive pattern provided on the substrate and disposed facing the third conductive pattern. On the circumference of the first, second, third and fourth conductive pattern disposing positions of the substrate, a ground potential part is disposed. Further, the first conductive pattern and the second conductive pattern disposed facing each other are connected by a first resistor, and the third conductive pattern and the fourth conductive pattern disposed facing each other are connected by a second resistor.
