Electronic heating/cooling garment and electronic heating/cooling device attachable to/detachable from garment

An electronic heating/cooling device, comprising:

• a temperature changing element that is configured to come in contact with skin covering a large blood vessel;
• a heating medium circulation path thermally coupled to an opposite surface of the temperature changing element from a surface that is configured to come in contact with the skin;
• a pump that is a part of the heating medium circulation path and is configured to circulate a heating medium;
• and
• a battery configured to supply electric power to the pump and the temperature changing element, wherein
• the heating medium circulation path is composed of a flexible, thermally conductive material having a tubular shape, holds the circulating heating medium in a tubular internal space in an airtight manner, and has a first electrode and a second electrode, the first and second electrodes being made of a flexible, electrically conductive material and being configured to supply the electric power from the battery to the temperature changing element and the pump,
• the heating medium circulation path has a flexible, electrically conductive material portion made of a flexible, electrically conductive material, and a flexible, non-electrically conductive material portion made of a flexible, non-electrically conductive material,
• the first electrode is a first flexible, electrically conductive material portion,
• the second electrode is a second flexible, electrically conductive material portion,
• a first flexible, non-electrically conductive portion is coupled between one end of the first flexible, electrically conductive material portion and one end of the second flexible, electrically conductive material portion, and
• a second flexible, non-electrically conductive material is coupled between the other end of the first flexible, electrically conductive material portion and the other end of the second flexible, electrically conductive material portion.
