PROBLEM TO BE SOLVED: To provide a high frequency switch module particularly applied to communication apparatuses or the like that can highly control its amplifier. SOLUTION: The high frequency switch module comprises: a switch circuit 7 connected to a terminal of an antenna 1; and a branching circuit 8 and a detection circuit 6 connected to the switch circuit 7, the switch circuit 7 is mounted on the surface of a laminated body 11 comprising a plurality of dielectric layers as a mount component 7a, the branching circuit 8 and the detection circuit 6 are mainly formed as electrode patterns 12, 12b, 12c in an inner layer of the laminated body 11, and the detection circuit 6 uses a transmission line interconnecting the switch circuit 7 and the branch circuit 8 for a major line 9.
