Claims

[Scope of utility model registration request]

An outer bobbin is provided with a flange having a hole for communicating with an external lead wire at one end of the winding drum, and an external lead is installed at the opposite end of the inner winding drum that is inserted into the winding drum of the outer bobbin. It consists of an inner bobbin provided with a flange having a hole for wire insertion, and this inner bobbin has a discontinuous section on the outer peripheral surface of the winding drum that separates the coil-wound part at the center and the non-wound parts at both ends. A coil bobbin characterized in that a protrusion is formed and the protrusion is brought into close contact with a winding drum of an outer bobbin.
