Claims

[Claims for Utility Model Registration] (1) A coil formed by laminating a plurality of flat coils formed by processing planar conductors, and a pair of ferrite magnetic cores sandwiching the coils. Thin transformer. (2) In the thin transformer according to claim 1, the input and output ends of the coils are led out in the same direction as the mounting surface of the thin transformer, and the lengths of the coils are shortened in the order closer to the mounting surface. A thin transformer characterized by being bent in a direction toward a mounting surface and connected to the mounting surface.
