Claims

[Claims for Utility Model Registration] A first cylindrical portion with a small diameter through which the core is inserted through the inner periphery;
A bobbin that has a double cylindrical structure with a large-diameter second cylindrical portion around which a winding wire is wound, and an intervening member formed by winding an insulating sheet with an electrode film formed on its surface. The interposed member is interposed between the outer circumferential surface of the first cylindrical portion and the inner circumferential surface of the second cylindrical portion, and the bobbin and the interposed member are disposed within a case. The intervening member is housed, an insulating resin is cast in the case, and each end of the electrode film on the inner circumferential side and the outer circumferential side of the wound intervening member is connected to the pin terminal of the bobbin, respectively. A transformer characterized by:
