An SPDT switch including a plurality of FETs for realizing a high-frequency switch having low distortion characteristics is provided. The SPDT switch includes a plurality of FETs, each of which receives a reception signal on a reception side and a grounding FET on a transmission side, FET series connection to connect the capacitances between the first gate and the source and between the second gate and the drain. Also, inductances are connected in parallel for a plurality of FET serial connections. Thus, a high-frequency switch having a low distortion characteristic at low voltage can be easily realized, and a 1dB suppression level, which is one index of input / output characteristics, can be improved by 5dB or more at an input level compared with a conventional SPDT switch.
