Claims

[Scope of utility model registration request]

It is equipped with a shield case from which three or more coaxial terminals are led out, and a printed circuit board mounted inside the shield case and equipped with a plurality of electronic components including an analog switch that can switch and connect the coaxial terminals. In a high frequency switch that operates the analog switch in response to a signal to switch the high frequency signal applied to the coaxial terminal, one surface of the printed circuit board forms a conductive pattern around the circuit pattern, and the other surface of the printed circuit board forms a conductive pattern around the circuit pattern. The high frequency switch is characterized in that a hole is formed through which a lead wire of the electronic component can be inserted, and a shield plate that passes through the printed circuit board and is connected to the conductive pattern is closely attached.
