COMMON MODE CHOKE COIL AND MANUFACTURING METHOD THEREOF, AND COMMON MODE CHOKE COIL ARRAY

摘要

PROBLEM TO BE SOLVED: To provide a common mode choke coil capable of easily realizing the adjustment of an impedance value by changing the thickness of an impedance value adjusting insulating layer as necessary. SOLUTION: The impedance value adjusting insulating layer 2 is formed on the entire of the main surface of a first magnetic substrate 1. A coil pattern and an insulating layer are alternately formed on the upper layer thereof. The insulating portion of any one of or both a center region surrounded by the coil pattern on each insulating layer other than the layer 2 and the coil pattern external peripheral region are removed. A resin containing magnetic powder is provided on an uppermost insulating layer 10 and on an insulating layer removed portion. A second magnetic substrate 13 is bonded via a bonding layer 12.
