PROBLEM TO BE SOLVED: To solve the problem that a high frequency switch circuit itself becomes complicated and enlarged by a configuration to be added for the purpose of suppressing an unwanted wave contained in a high frequency signal or releasing a leaked high frequency signal leaked to a switch changeover control signal line. SOLUTION: In the high frequency switch circuit having a plurality of input/ output terminals and a switching element for transmitting the high frequency signal from a high frequency signal transmission line between the input/output terminals selectively connected in accordance with a control signal applied from the switch changeover control signal line and proximately locating the switch changeover control signal line and the high frequency signal transmission line, the switch changeover control signal line has a line length as long as the odd multiple of 1/4 wavelength of the unwanted high frequency signal contained in the high frequency signal.
