ABSTRACT:
A multilayered coil is formed by inserting insulating paper13having either a pressure sensitive adhesive or an adhesive disposed on both faces thereof into at least one place between thin coil layers and then magnetic cores15are mounted to the multilayered coil from above and below. Thus, a thin transformer for a switching power supply is provided, in which variation in distance between coil11and coil12, of which one is disposed over the other, variation in distance of coil11and coil12from magnetic core15and the like are suppressed.
