Abstract
A substantially loop-shaped inductor including a via electrode is arranged such that its loop surface is parallel to a mounting board. Thus, a direction of magnetic flux of the inductor is perpendicular to the mounting board, and influence of the magnetic flux on an adjacent electronic component is significantly reduced and minimized. In addition, the via electrode defines a principal portion of the inductor. Thus, an inductor with a great Q value is obtained, and the insertion loss of a laminated LC filter is significantly reduced and minimized.
