The auxiliary ground layer is a part in which the main line and the sub line do not overlap in the lamination direction and is disposed to face a part in which a distance from the first ground layer and a distance from the second ground layer are different in the lamination direction. When a longer distance is set as a first distance a and a shorter distance is set as a second distance b between a distance between the non-overlapping part and the first ground layer and a distance between the non-overlapping part and the second ground layer, and a third distance between the non-overlapping part and the auxiliary ground layer is set as c, the relationship of a>c≥b is satisfied.
