Provided is a high-frequency module in which the size and the cost can be reduced. A high-frequency module (1) in which an LC filter (2), which has an inductor formed by a thin-film process and a capacitor formed by a thin-film process, and a piezoelectric resonator (3), which functions as a trap filter that is serially connected to the LC filter (2) and that has a resonance frequency outside the pass-band of the LC filter (2), are connected to each other. |
