To provide a bidirectional switch operational at a high voltage and capable of reducing a loss at the time of switching.
A bidirectional switch 1, which is a switch for bidirectionally switching a current direction flowing between first and second terminals 1a, 1b, includes: a first series connection circuit 10A including a first semiconductor switch element 20A having no resistance in a reverse direction and a first counter-flow prevention diode 30A connected in series with the first semiconductor switch element 20A in a forward direction; and a second series connection circuit 10B including a second semiconductor switch element 20B having no resistance in a reverse direction and a second counter-flow prevention diode 30B connected in series with the second semiconductor switch element 20B in a forward direction. The first series connection circuit 10A and the second series connection circuit 10B are connected in parallel between the first and second terminals 1a, 1b in such a manner that the forward directions of the first and second semiconductor switch elements 20A, 20B are oppositely directed.
