Abstract
A filter element is mounted on a module substrate. The filter element includes a ground terminal and a pair of signal terminals. The module substrate includes a ground plane, a ground land, and an inductance adjusting line that connects the ground land to the ground plane. The ground terminal of the filter element is connected to the ground land of the module substrate. The inductance adjusting line includes an in-plane extending portion that extends in an in-plane direction of the module substrate.
