Abstract:
A laminated inductor includes: 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 all of the conductor patterns constituting the coil body are either a 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, and wherein the number of C-shaped patterns in the coil body is greater than that of line-shaped patterns.
