PROBLEM TO BE SOLVED: To provide a high frequency module which improves reception sensitivity without causing any increase in current consumption or cost. SOLUTION: The high frequency module has: a mixer circuit 203 performing frequency conversion by mixing a local oscillation signal and a received signal; a filter circuit 205 for removing the unnecessary frequency components from the output signal of the mixer circuit 203; and an amplifier circuit 210 for amplifying and outputting the output signal from the filter circuit 205 while controlling gain, wherein one or more resistance elements R1a and R1b are inserted in series between the output end of the amplifier circuit 210 and the input end of a demodulation circuit being connected to the post-stage thereof.
