Abstract: An electronic heating/cooling garment includes: a neck part, a collar (neckband), or an underarm part where a Peltier device (31) is placed; and a front body or a back body where a heating medium circulation path (35) and a battery (35) are placed, the battery (35) being configured to supply electric power to a pump (341) and the Peltier device (31). The heating medium circulation path (35) is composed of a flexible thermally conductive material having a tubular shape and holds a heating medium therein in an airtight manner. The heating medium circulation path has a first electrode and a second electrode on its outer surface. The first and second electrodes are configured to supply the electric power from the battery (35) to the Peltier device (31) and the pump (341).
