Patent number: 5515022Abstract: A multilayer inductor 1 is fabricated, for example, by sandwiching a first magnetic material sheet (21) between a second magnetic material sheet (22) and a third magnetic material sheet (23) and integrating the three layers. The first magnetic material sheet (21) is preferably at least 0.2 mm thick and has a first spiral conductor pattern (31) having an extreme lead-out portion (310) formed on its upper major surface. The first sheet (21) is provided with a through-hole (4) extending between the opposed major surfaces and having a larger diameter on the conductor pattern bearing surface. The through-hole (4) is filled with a conductor (35) contiguous to the first conductor pattern (31). The second magnetic material sheet (22) has a second spiral conductor pattern (32) having an extreme lead-out portion (320) formed on its upper major surface and connected to the conductor (35) in the through-hole (4).Type: GrantFiled: August 3, 1994Date of Patent: May 7, 1996Assignee: TDK CorporationInventors: Kouji Tashiro, Akira Kaneko
