PROBLEM TO BE SOLVED: To reduce an insertion loss of the high frequency circuit by employing a micro machine switch for its switching element and to improve the high frequency characteristic of a circuit employing this high frequency circuit. SOLUTION: The high frequency circuit is provided with a 1st high frequency signal block means 7 that is connected to a 1st control signal line 6, through which a control signal S is applied to the micro machine switches 4a, 4b, and blocks the passing of a high frequency signal RF.
