Abstract:
1. A laminated inductor having a component body that provides a mounting surface on one face of the component body, and at least a pair of external electrodes formed on the mounting surface, wherein: the component body has a laminate constituted by multiple insulator layers, a spiral coil conductor formed in the laminate, and leader parts that electrically connect the coil conductor and the external electrodes, respectively; the coil conductor comprises multiple conductor patterns formed in the insulator layers and via hole conductors that penetrate through the insulator layers and electrically connect the multiple conductor patterns in a direction parallel to the mounting surface, constituting turn units, wherein a coil axis runs roughly in parallel with the mounting surface and roughly perpendicularly to the turn units, said turn units having sides roughly in parallel with and perpendicular to the mounting surface, respectively; and all of the via hole conductors are formed only on a side farthest away from the mounting surface among the sides of the turn units, wherein the conductor pattern comprises a combination of a C-shaped pattern constituted by a polygonal shape having three or more apexes and having a part of one side missing, and a bar-shaped pattern constituted by a roughly straight line shape, the bar-shaped pattern is longer than a length of the missing part of the C-shaped pattern, and the bar-shaped pattern constitutes at least a part of the side farthest away from the mounting surface.
