The phase shifter carries out on/off control of a micromachine switch to switch pass phases of high-frequency signals. The micromachine switch includes one end fixed to second distributed-constant circuits (3a, 3b) and the other end having cantilevers (11a, 11b) capable of making contact with first distributed-constant circuits (2a, 2b). The micromachine switch further includes first insulators between the first distributed-constant circuits (2a, 2b) and the cantilevers (11a, 11b), and second insulators (15a, 15b) that cooperate with the first insulators to hold the voltage of a first control signal.
