PROBLEM TO BE SOLVED: To suppress occurrence of crack due to thermal stress, by maintaining the original insulation performance of an insulation sheet arranged between winding conductors.SOLUTION: A mold transformer includes a core, a secondary winding wound around the core, and a primary winding wound around the secondary winding. An insulation sheet is placed between the layers of winding conductor wound by multiple number of turns in the primary winding and secondary winding, and they are resin molded integrally. A hole is formed in at least a part of the insulation sheet, and filled with the resin. |
