A micromachine switch for use in a millimeter wave circuit and a microwave circuit is simpler in structure than conventional micromachine switches. The micromachine switch has first and second high-frequency signal lines (1b, 1a), cantilever (11) fixed to an end of the first high-frequency signal line (1b) and extending to a position above second high-frequency signal line (1a), first insulating means (15) disposed on second high-frequency signal line (1a), second insulating means (14) disposed in an area where cantilever (11) and second high-frequency signal line (1a) confront each other, and first control signal line (2) connected between an end of second high-frequency signal line (1a) and first insulating means (15), for applying a control signal. When the control signal is applied to second high-frequency signal line (1a), cantilever (11) is attracted to second high-frequency signal line (1a), and connected to second high-frequency signal line (1a) via second insulating means (14) in a high-frequency fashion.
