<p>PURPOSE:To enable to make efficient use of the entire space in a case by a method wherein the winding part of the coil of a coil bobbin is placed in the case shifting toward the side of one lateral face. CONSTITUTION:The wound part 17 of the coil bobbin 14 having flanges 16a and 16b, whereon a terminal pin 15 is erected on both ends, is provided by shifting on the side of one side face from the center in lateral direction of the flanges 16a and 16b. On this coil bobbin 14, a core 20 consisting of ferrite and the like is incorporated, and a transformer part 21 is constituted. This transformer part 21 is placed in a case 26 without leaving a space, and the electronic part 22 of a rectification block part 25 is arranged at the space part located on the other side of the transformer part 21, thereby enabling to prevent the generation of a wasteful space.</p> |
