PROBLEM TO BE SOLVED: To provide an antenna switch module capable of preventing breakage of elements that is caused by electrostatic surge, with no degradation in transmission/reception signals. SOLUTION: The antenna switch module in a first embodiment comprises a first terminal, a plurality of second terminals, a switch circuit for selectively connecting one of the plurality of second terminals to the first terminal, and a surge absorbing circuit provided between the switch circuit and the first terminal. The surge absorbing circuit comprises a first inductor provided with one end that is connected to the first terminal; a second inductor electromagnetically connected to the first inductor, which comprises one end that is connected to the other end of the first inductor as well as the other end connected to the switch circuit; and a surge absorbing element that comprises one end connected to the other end of the first inductor as well as to one end of the second inductor, and the other end connected to a ground terminal.
