Patent ID: 8669839

Claim:
A laminated inductor comprising: a laminate constituted by multiple insulator layers; external electrodes formed on the outside of the laminate; and a coil conductor formed spirally inside the laminate; wherein the coil conductor has leaders that electrically connect to the external electrodes and a coil body other than the leaders; wherein the coil conductor has conductive patterns formed on the insulator layers, and via hole conductors that penetrate through the insulator layers and electrically connect the multiple conductor patterns; wherein a conductor pattern formed on some insulator layers represents a C-shaped pattern that includes four corners, and has an open part on one side, of a roughly rectangular shape, and a conductor pattern formed on other insulator layer(s) is a line-shaped pattern corresponding to the open part of one side of the C-shaped pattern of the roughly rectangular shape; wherein all of the conductor patterns constituting the coil body are either the C-shaped pattern or line-shaped pattern; wherein the coil body has a partial structure where two or more C-shaped pattern layers are stacked together successively; wherein the number of C-shaped patterns in the coil body is greater than that of line-shaped patterns; and wherein a length of the line-shaped pattern is equal to or less than 30% of a total length of the four sides of the roughly rectangular shape constituting the C-shaped pattern.
