发明名称 LAMINATED INDUCTOR
摘要 PROBLEM TO BE SOLVED: To provide a structure, capable of improving the efficiency of an inductor being acquired thereby, in a laminated inductor where one or more turns of coil conductor portions are formed at certain heights, and the plurality of coil conductor portions are connected electrically with each other through via-hole electrodes. SOLUTION: A laminated inductor has a ceramic sintered body made of magnetic ceramics, wherein one or more turns of coil conductor portions are formed at their certain heights and its winding circuit comprises the plurality of coil conductor portions connected electrically with each other through via-hole electrodes. Furthermore, in the inside of its winding circuit, the portions where upper and lower coil conductor portions 6, 7 are connected electrically with each other through a via-hole electrode 11 are so formed that they are positioned more internally than the winding circuit comprising the upper and lower coil conductor portions 6, 7. That is, a terminated end 6b of the coil conductor 6 and a started end 7a of the coil conductor portion 7 are both bent inside the winding circuit, when they are seen in a plan-view.
