COIL PART AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a coil part that achieves improved characteristics and reduced size by finely fabricating a spiral conductor, while exhibiting high electrical reliability, and to provide a method of manufacturing such a coil part. SOLUTION: A common-mode choke coil 100 includes a laminate having a magnetic substrate 10A and a first insulating resin element 11a formed on the magnetic substrate 10A, a first terminal electrode 17a provided at the side face of the laminate, a first extraction electrode 14a that is provided in contact with the top face of the magnetic substrate 10A and one end 14a1of which is connected with the first terminal electrode, and a first spiral conductor 15a that is formed on the first insulating resin element 11a to be electrically connected with the first terminal electrode 17a. The first extraction electrode 14a is formed to be larger in width than the first spiral conductor 15a. COPYRIGHT: (C)2009,JPO&INPIT
