Abstract
A switch device includes a common terminal, a switch circuit configured to switch between states of conduction between terminals, a switch circuit configured to switch between states of conduction between terminals, and a switch circuit configured to switch between states of conduction between at least one of terminals and a terminal. Switch elements are provided which are disposed on a path connecting the terminals, a path connecting the terminals, a path connecting the terminal and one of the terminals, and a path connecting the terminal and the other one of the terminals, respectively. The above switch element is formed of one or more stacked semiconductor elements, and the number of stacks of the semiconductor elements in the switch element is smaller than that in the switch element.
