| 摘要 | PURPOSE:To contrive thinning of the title transformer by a method wherein a primary coil and a secondary coil are spirally formed on both sides of an insulated plate having a through hole in the center part, and after an insulating film has been covered, a magnetic material is formed thereon. CONSTITUTION:A through hole 1a is provided in the center part of a round and thin insulated plate 1. A spiral primary coil conductor 2 is formed by patterning on the upper surface of the round insulated plate 1, a spiral secondary coil conductor 3 is formed by patterning on the lower surface of the insulated plate 1, and then electrode parts 2a, 2b, 3a and 3b are provided. After primary lead-out wires 2c and 2d have been connected to the electrode parts 2a and 2d, and secondary lead-out wires 3c and 3d have been connected to electrode parts 3a and 3b, an insulating film 4 is formed on the whole surface. Then, a magnetic material 5 whereon powdery magnetic material bonded by binder is applied is formed on the upper surface of the insulating film 4. As a result, the thickness of the entire transformer can be reduced to 0.5mm. or thereabout. | ||||||
