Claims

[Scope of utility model registration request]

A plurality of mouth-shaped cores and I-type cores made by punching materials such as silicon steel plates without loss are laminated to form a mouth-shaped core and I-type core, and a coil is wound around this ■-shaped core with I-. A thin transformer characterized by being fixed to a mouth-shaped iron core.
