PURPOSE:To fix the leadout position without winding an insulation tape by providing protrusion and cut-out part to the upper end collor of each bobbin and winding a lead wire to a metal pin terminal after hooking the winding end lead to such protrusion. CONSTITUTION:An upper end collor 14 is provided to the upper part of a primary bobbin 10 and a lower collor 17 to the lower part thereof. A square column type protrusion 15 protruded upward is provided to a part of the external circumference of the upper end collor 14 and a pair of cut-out grooves 16 are also provided in such a manner as interposing such protrusion. A plurality of leadout grooves 27 are provided to the lower end collor 17 and a metal pin terminal 18 is provided at the lower surface. The starting end of lead wire 1S is wound several times to the metal pin terminal 18, and the winding 1 is wound by the specified turns to the internal wall 14a of the upper end collor 14 with the specified tension from the internal wall 17a of the lower end collor 17. The winding end lead wire 1f is further hooked to the square column protrusion 15 through a cut-out groove 16 provided to the upper end collor 14, led out to the lower side in straight through the other cut-out groove 16 and is then wound to the metal pin terminal 18 through the leadout groove 27.
