Abstract

PURPOSE:To absorb a dislocation by means of elastic force of a bobbin even if dimensions of a ferrite core is dislocated a little by winding a coil on the bobbin formed of resin in which magnetic powder is mixed and welding both ends of the bobbin to the inwall of the ferrite core with pressure applied respectively. CONSTITUTION:A bobbin 8 formed by resin in which magnetic powder is mixed is equipped with flanges 8a, 8b on both ends thereof and its core part is not hollow. After the bobbin 8 and a coil 2 wound thereon are accommodated, ferrite cores 6, 7 are attached to each other by a bonding agent and the like. Since at this time one end of the bobbin 8 is welded to a plate part 6a with pressure applied, the other end to a bottom part 7a with pressure and the bobbin 8 has elastic force, a dislocation is absorbed by the elastic force of the bobbin 8 and a gap therebetween is not produced even if the dimensions of a ferrite cores 6, 7 are dislocated from the designed dimensions a little.
