Assignee: TAIYO YUDEN CO., LTD.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. 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 multilayered 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 and being in contact with the first surface, at least a part of the filter circuit being located at a side of the second surface;
a line located between the first surface and the second surface in the multilayered substrate, the line being located closer to the first surface than the filter circuit, 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 is in contact with 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 area of the region where the line overlaps with the ground terminal in the plan view is equal to or greater than ½ of an area of the line in the plan view.
