PROBLEM TO BE SOLVED: To provide a winding structure with which insulation distance between windings can be secured. SOLUTION: A coil wining 1 is formed of a metal plate, wherein the winding is obtained by forming a shape in which almost annular winding plates 2, 3 and a half-arc half-winding plate 4 are mutually connected. On the inner radius sides of winding portions 6, 26 and of a half-winding portion 15, tabs 11, 16 and 31 are formed, respectively. When the coil winding 1 is mounted on an E-shaped core 40, tabs 11, 16 and 31 are bumped against the center leg of the E-shaped core 40, resulting in keeping a distance of a size of the tabs 11, etc. between the inner radius portions except the tabs 11, etc. of the winding plates 2, 3 and of the half-winding plate 4 and the center leg, and consequently securing a creeping distance in the horizontal direction.
