PURPOSE:To improve the assembly working properties, by winding an insulator- coated conductor into a substantially rectangular shape to form each of coils, and winding a flexible magnetic material around the coils placed in parallel thereby to form a rolled core passing through hollow parts of the winding coils. CONSTITUTION:An insulator-coated conductor 6 is wound into a substantially rectangular shape to form each of a primary winding coil 4 and a secondary winding coil 5. With one sides 4a, 5a of the winding coils 4, 5 placed in parallel to each other, a ribbon-shaped flexible magnetic material 7 is wound around both the sides 4a, 5a placed in parallel to form a rolled core 1 passing through hollow parts 4b, 5b of the winding coils 4, 5. A rolled core bobbin has a gear part 11 formed at its upper end, and is radially divided into two bobbin parts 101, 102. The bobbin is rotated by means of a motor or the like through the gear part 11. Thus, it is possible to produce a rolled core type transformer in a single winding operation. |
