PROBLEM TO BE SOLVED: To solve the problem that, when forming electrodes, plating grows, resulting in a decline in insulation resistance between the electrodes and in an increase in frequent defects of short circuits between the electrodes. SOLUTION: A ferrite core 6 has such a structure that sword guard-like portions 1 are formed on both ends of a winding core 4, with a plurality of legs 2 formed continuously with each sword guard-like portion 1, and an electrode 3 is formed in an end on the bottom side of each leg 2. In the ferrite core 6, each leg 2 is tapered toward the bottom face thereof, and a ridgeline on the side face of each leg 2 is formed into a curved surface. COPYRIGHT: (C)2005,JPO&NCIPI
