A high-frequency module includes a switch IC. An antenna filter is connected to a common terminal of the switch IC and arranged adjacent to an antenna. The antenna filter is a low-pass filter whose attenuation band includes higher harmonic frequency bands of GSM1800/GSM1900 transmission signals and TDS-CDMA transmission signals. An individual-terminal filter is connected to one individual terminal of the switch IC. The individual-terminal filter is a low-pass filter whose attenuation band includes higher harmonic frequency bands of GSM850/GSM900 transmission signals.
