PURPOSE:To prevent the change of the width of a conductor between a metallic sheet and a lead section, and to obviate current concentration in the lead section by bending the metallic sheet in the width direction of a winding under the state in which the metallic sheet is superposed on an insulating sheet and using the terminal section of the metallic sheet as the lead section as it is. CONSTITUTION:With a metallic sheet 16, an insulating sheet 17 is superposed on the inside of its final turn section, it is bent in the width direction of a winding from a polygonal line (l) section at 45 deg., and the terminal section of the metallic sheet 16 upward projecting from the upper end section of the winding is used as a lead section. Accordingly, the partial heating of the lead section due to current concentration can be prevented without changing current distribution extending over the whole width of the metallic sheet because the lead section is led out without altering conductor width up to the lead section from the winding. |
