Claims

[Scope of utility model registration request]

A bobbin in which a primary winding and a secondary winding are wound between the middle collar and the collars at both ends, a spacer attached to the bobbin so as to cover the winding, and a spacer combined with the bobbin. In a power transformer consisting of a core, the spacer is shaped to have a flange that abuts one flange surface of the middle flange, and the spacer is in a state where the flange abuts one flange surface of the middle flange. The power transformer is configured such that the first flange surface of the inner flange forms part of the creepage distance between the primary winding and the secondary winding.
