Claims

[Scope of utility model registration request]

A wire is wound around a cylindrical plate core in which a cylindrical core protrudes from approximately the center of the rectangular plate core, and T-shaped recesses for attaching electrodes are provided on opposite end faces of the rectangular plate core with the cylindrical plate core in between. A T-shaped electrode conductor plate with a cross-shaped head bent upward is provided in the T-shaped recess, and the bent head portion of the T-shaped electrode conductor plate serves as a bent terminal where both ends of the winding are connected. A rectangular core that forms a closed magnetic circuit is joined to the cylindrical plate core by soldering to form a joint core having a rectangular external shape, and then both legs of the T-shaped electrode conductor plate are connected along the joint core. A chip coil characterized by being folded to form a surface mount terminal.
