器。[Claims for Utility Model Registration] 1. A winding frame having a cylindrical winding core portion, a winding portion applied to the outer periphery of the winding core portion, and a core combined with the winding frame; is a first part inserted inside the winding core part, a second part facing the outer circumferential surface of the winding part at a distance in the radial direction, and a space between the first and second parts. In the current transformer, the first part has at least a surface facing the outer peripheral surface of the winding part and both side surfaces adjacent to the surface. A current transformer characterized in that a boundary portion is rounded to prevent damage to an insulating portion of an electric wire passing through a radial interval between the first portion and the winding portion. 2. The current transformer according to claim 1, wherein the first portion has a circular cross section.
