PROBLEM TO BE SOLVED: To obtain a coil for electromagnetic equipment such as a transformer, reactor, etc., or an electric element for capacitor, etc., which can be improved in both resource conservation and recyclability and dielectric breakdown characteristic. SOLUTION: In electronic equipment, the interfacial dielectric breakdown strengths between a molded resin 9 and insulating sheet materials are improved by making the interfacial distances between the resin 9 and sheet materials longer in such a way that the sheet materials are wound around an original coil composed of a conductor 8 and an interlayer insulating material 7, in such a way that the outermost third insulating sheet material 6 becomes higher in height than the first and second insulating sheet materials 4 and 5 and forming the molded resin 9 in the recessed section between the third sheet material 5 and the end sections of the blank coil. In addition, the dielectric breakdown strengths of the routes from the interfaces between the laminated layers to the end sections are improved by forming the resin on the end sections of the first and second sheet materials 4 and 5.
