Claims

[Scope of utility model registration request]

A resin molded coil made by concentrically winding a high-voltage coil and a low-voltage coil with a main insulating layer interposed between them, and impregnating or casting a synthetic resin into both coils, and a resin molded coil made by attaching an iron core to the resin-molded coil. By providing stepped portions on the iron core so as to come into contact with both surfaces on the low-voltage coil side of the resin-molded coil in the shape transformer, the air layer between the iron core and both surfaces on the high-voltage coil side of the resin-molded coil is almost constant. A resin mold type transformer characterized in that it is configured to have a gap between.
