PROBLEM TO BE SOLVED: To provide a resin mold coil in which occurrence of partial discharge is suppressed sufficiently around a coil conductor by enhancing the impregnation properties of a thermosetting resin, and to provide a manufacturing method therefor and a mold transformer.SOLUTION: When manufacturing a resin mold coil having a cylindrical core 2, a coil conductor 3 wound on the outer periphery of the core 2 in multilayer, and an insulating sheet 4 for insulating between the layers of the coil conductor 3, a linear object 11 thinner than the coil conductor 3 is wound spirally on the outer periphery of the coil conductor 3 at a pitch of not bringing the linear objects into contact with each other. Thereafter, the coil conductor 3 is wound on the outer periphery of the core 2, and after interposing the insulating sheet 4 between the inner peripheral side conductor and the outer peripheral side conductor of the coil conductor 3, the circumference of the coil conductor 3 is molded of a thermosetting resin 5. |
