Abstract: A laminated inductor includes a component body that provides a mounting surface on one of its faces, and at least a pair of external electrodes are 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 external electrodes; the coil conductor comprises conductor patterns formed in the insulator layers and via hole conductors that penetrate through the insulator layers and electrically connect the multiple conductor patterns, and also has a coil axis running roughly in parallel with the mounting surface and a turn unit having one or more sides running roughly in parallel with the mounting surface; and the via hole conductors are formed only on the side farthest away from the mounting surface among the one or more sides.
