Abstract
A laminated inductor includes 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 electrically connect the multiple conductor patterns; wherein conductor patterns formed on some insulator layers each represent a C-shaped pattern that includes the four corners and has an open part on one side, of a roughly rectangular shape, while a conductor pattern formed on other insulator layer(s) represents a line-shaped pattern corresponding to the open part of one side of the aforementioned C-shaped pattern of the roughly rectangular shape; and wherein an insulator layer on which the C-shaped pattern is formed, and insulator layer(s) on which the line-shaped pattern is formed, adjoin each other at least in one part of the laminate.
