PROBLEM TO BE SOLVED: To provide a high-frequency signal channel changeover switch which can suppress the continuity loss of a high-frequency signal. SOLUTION: A plurality of signal lines 4a, 4b, and 4c on a signal continuity control side with continuity on/off control means 6 of a high-frequency signal and a signal line 3 on a non-control side without the continuity on/off control means 6 are included. The signal lines 3, 4a, 4b, and 4c are assembled in a common portion X to be connected, and the high-frequency signal is outputted through the signal lines 3 and 4. An impedance of a signal line from a connection X to the continuity on/off control means 6 is adjusted in respective signal lines 4a, 4b, and 4c, so that a formed position of the continuity on/off control means 6 observed from the connection X may be an appearance open end of the high-frequency signal with a set frequency. A portion of the high-frequency signal energizing the connection portion X flows through the signal line 4 side with the continuity on/off control means 6 in an off state, thereby preventing a loss.
