Abstract
A bidirectional switch includes a semiconductor element and a substrate potential stabilizer. The semiconductor element includes a first ohmic electrode and a second ohmic electrode, and a first gate electrode and a second gate electrode, which are sequentially formed on the first ohmic electrode between the first ohmic electrode and the second ohmic electrode. The substrate potential stabilizer sets a potential of the substrate lower than higher one of a potential of the first ohmic electrode or a potential of the second ohmic electrode.
