A high frequency module includes a first external connection terminal, a second external connection terminal, a filter unit, a first matching circuit, and a second matching circuit. The filter unit is connected between the first external connection terminal and the second external connection terminal. The first matching circuit is connected between the first external connection terminal and the filter unit. The second matching circuit is connected between the second external connection terminal and the filter unit. The first matching circuit and the second matching circuit are inductively or capacitively coupled to each other.
