PROBLEM TO BE SOLVED: To fix by inserting a primary coil into the inner periphery of a bobbin of a secondary coil and simultaneously electrically connect an end part on a first winding side of a secondary electric wire of the secondary coil with one end part of a primary electric wire of the primary coil without soldering. SOLUTION: A support wall 25 for supporting a conductive pin 22 is provided, and a cutout part 31 is formed in a part of a lower end of this wall. Further, a stopper collar 41, a conductive piece 43 and a mating part 44 are provided at the front end part of a primary bobbin, whereby one end part of a primary electric wire of a primary coil is electrically connected with an end part on a first winding side of a secondary electric wire of a secondary coil via the conductive pin 22 and the conductive piece 43. A pair of elastic detents 33 projecting backward are provided on the rear plane of a collar on a terminating winding side of a secondary bobbin, and an engagement part 48 at the rear end part of the primary bobbin penetrating the secondary bobbin is engaged with the elastic claw, to fix the primary coil on the inner periphery of the secondary bobbin to be fixed immovably in the longitudinal direction. |
