PROBLEM TO BE SOLVED: To obtain a high frequency switch which transmits and switches a signal with low loss. SOLUTION: A common terminal Pc and a third individual terminal Pp3 are connected by continuous transmission lines TL0, TL1, TL2 and a switch SW3. A connection point of the transmission lines TL0, TL1 is connected to a first individual terminal Pp1 through a switch SW1. A connection point of the transmission lines TL1, TL2 is connected to a second individual terminal Pp2 through a switch SW2. As for a line length L1 of a transmission line TL1 and a line length L2 of a transmission length, total electric length DL1+DL2' for a first communication signal S(f1) is less than 1/4 of a wavelength of the first communication signal S(f1). Moreover, as for a line length L2 of the transmission line TL2, an electric length DL2 for a second communication signal S(f2) is less than 1/4 of a wavelength of the second communication signal S(f2).
