Zusammenfassung:PROBLEM TO BE SOLVED: To reduce generation of a whining sound of a casing core which is formed by housing a toroidal core in a case. SOLUTION: As for the casing core which is formed by housing a toroidal core 1 formed by winding a band-like metal foil in a hard resin case 2, a silicon resin layer 4 is formed by applying a silicon resin to an inner surface of the case 2 and thereafter curing it. The toroidal core 1 is housed inside the case 2 and an opening of the case 2 is covered with a lid 3 wherein a silicon resin layer 4 is formed. COPYRIGHT: (C)2005,JPO&NCIPI
