Claims

[Scope of utility model registration request]

It has a cylindrical part into which the core is inserted and a coil is wound around the outer periphery, a flange part provided at both ends of the cylindrical part, and a terminal fitting that is locked to the flange part. The portion is provided with a locking piece that protrudes approximately perpendicularly to the plate surface of the flange portion and has a bent end whose tip is approximately parallel to the plate surface of the flange portion. One end is inserted between the bent end of the locking piece of the collar and the plate surface of the collar, and is engaged with the locking piece in the longitudinal direction of the terminal fitting. A coil bobbin with a retaining part.
