PROBLEM TO BE SOLVED: To provide a high-frequency circuit using a micro-machine switch capable of preventing a power loss of a high-frequency signal without causing poor conduction, and a wireless communication device using the same. SOLUTION: The micro-machine switch 11 switches whether or not to output the high-frequency signal input from an input terminal 16 to an output terminal 17 by switching between an on-state and an off-state. A DC voltage source 14 applies a DC voltage between contacts of the micro-machine switch 11 and allows a DC current to flow between the contacts of the micro-machine switch 11 when the micro-machine switch 11 is in the on-state. A high-frequency prevention circuit 13a prevents the input high-frequency signal from flowing into the DC voltage source 14. COPYRIGHT: (C)2007,JPO&INPIT
