Abstract:
1. A laminated inductor comprising a laminate constituted by multiple insulator layers, and a coil conductor formed in a spiral shape inside the laminate; wherein the coil conductor has conductor patterns formed on the insulator layers, and via hole conductors that penetrate through the insulator layers and which electrically connect the multiple conductor patterns; wherein a first conductor pattern formed on an insulator layer among the insulator layers consists of a C-shaped pattern that includes four corners and has an open part on one side, of a roughly rectangular shape, while a second conductor pattern formed as the only conductor pattern on another insulator layer among the insulator layers consists of a straight line-shaped pattern disposed to close the open part of one side of the C-shaped pattern of the roughly rectangular shape as viewed from above when the insulation layer with the first conductor pattern and the insulation layer with the second conductor pattern are stacked; wherein the insulator layer with the first conductor pattern and the insulator layer with the second conductor pattern are alternately stacked multiple times at least in one part of the laminate, wherein the first and second conductor patterns are electrically connected via hole conductors; and wherein the open parts of all of the C-shaped patterns on the insulator layers face the same side of the laminate as viewed from above.
