Claims

[Scope of utility model registration request]

In an I-lance whose core is a bobbin wound with multiple wires, an insulating cover in which a substantially arc-shaped groove is formed in the longitudinal direction of a square prism-shaped flexible insulating material is placed close to the flanges at both ends of the bobbin. A transformer characterized in that a winding portion is covered with a winding portion so as to increase a creepage distance between the plurality of winding wires.
