1. A mold transformer comprising a core, an insulator covering the core, and a heat-dissipating path configured to move heat from the core to an external space of the insulator, wherein the heat-dissipating path includes a hole provided in the insulator so as to extend in a direction from the external space toward the core, and
wherein the heat-dissipating path includes a member formed from an insulating material having higher thermal conductivity than the insulator,
the heat-dissipating path is located at a position away from a virtual line passing through a center of the core and parallel to the direction.
