Classification: CPC H | IPC H

Claim 6:
7. A filter comprising:
a first signal terminal;
a second signal terminal;
a filter circuit connected between the first signal terminal and the second signal terminal;
a substrate having a first surface and a second surface opposite from the first surface, the first signal terminal and the second signal terminal being located on the first surface, at least a part of the filter circuit being located at a side of the second surface;
a line located closer to the first surface than the filter circuit in the substrate, a first end of the line being connected to one of the first signal terminal and the second signal terminal; and
a ground terminal that is located on the first surface and to which a second end of the line is connected, an area of a region where the line overlaps with the ground terminal being greater than an area of a region where the line overlaps with the one of the first signal terminal and the second signal terminal when the substrate is viewed in a plan view,
wherein:
the line is provided in plural,
the ground terminal is provided in plural so as to correspond to the lines, each of the ground terminals being connected to corresponding one of the lines,
one of the lines is connected to the first signal terminal, and an area of a region where the one of the lines overlaps with the corresponding ground terminal is greater than an area of a region where the one of the lines overlaps with the first signal terminal when the substrate is viewed in the plan view, and
another one of the lines is connected to the second signal terminal, and an area of a region where the another one of the lines overlaps with the corresponding ground terminal is greater than an area of a region where the another one of the lines overlaps with the second signal terminal when the substrate is viewed in the plan view.
