Title: Laminated electronic part
Inventor: SAKURAI SATOSHI
IPC: H01F27/29
Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To solve a problem in which insulating layers and conductor pattern layers are increased in number of layers so as to attain a prescribed inductance because a line cannot be increased in length per insulating layer, an insulating layer is increased in thickness per turn, and a magnetic flux is liable to leak out because an insulating layer is liable to get thicker in a part between the ends of the conductor pattern where no conductor pattern resides than in other parts between the conductor patterns. SOLUTION: An insulating layer and a conductor pattern which is formed on the insulating layer and possessed of a loop that is partially cut out and whose one end is extended toward the center of the insulating layer are alternately laminated. The conductor patterns each interposed between the insulating layers are successively connected to constitute an inductor in the laminate. Therefore, a magnetic flux leaks less than usual, and a laminated electronic part of this constitution can be more enhanced in inductance than usual with a less number of layers composed of conductor patterns and insulating layers.
