A high-frequency module includes an inductor and an ESD protection element. The inductor is a circuit element defining a low pass filter, and includes parasitic capacitance between a signal line and a ground in a specific frequency band. The ESD protection element transfers a surge current flowing through a signal line to the ground, includes a capacitor in a specific frequency band, and has a configuration in which the capacitor and the parasitic capacitance of the inductor are connected in parallel.
