A high-frequency module includes a wiring board, a first duplexer that separates a transmission signal and a reception signal in a first frequency band, and a second duplexer that separates a transmission signal and a reception signal in a second frequency band whose reception-side frequency band partially overlaps with a frequency band of a third-order harmonic of the first transmission signal. The first duplexer is disposed near a predetermined side on a first main surface of the wiring board, and the second duplexer is disposed near an opposite side opposing the predetermined side. An extended line extending from a first transmission terminal of the first duplexer and an extended line extending from a second reception terminal of the second duplexer are spaced away from each other.
