<p>PROBLEM TO BE SOLVED: To provide a coil bobbin-cum-iron core holder for a high-frequency transformer that can hold an amorphous wound iron core on the assumption that the amorphous wound iron core is used as it is after annealing, and around which a primary coil and a secondary coil can be wound, and to provide a high-frequency transformer using the same.SOLUTION: A coil bobbin-cum-iron core holder for a high-frequency transformer consists of a synthetic resin frame body 1 comprising: a pair of iron core holding parts 6 and 6 holding an amorphous wound iron core 3 configured by annealing an amorphous magnetic steel strip wound a predetermined number of times in a cylindrical shape; and a pair of coupling parts 7 and 7 coupling the iron core holding parts at a predetermined interval. The frame body is divided at an intermediate part of both iron core holding parts; and two opposed pairs of divided iron core holding parts 6A and 6B comprise, at end parts, engaging parts 8 and 9 that can be coupled with each other in a state where the amorphous wound iron core are externally inserted. A coil holding part 10 for winding a coil strand for a high frequency wave is continuously formed outside both coupling parts and inside both iron core holding parts.</p> |
