PROBLEM TO BE SOLVED: To appropriately adjust the temperature of a user's carotid artery. SOLUTION: A temperature control unit 11 of a body temperature controller includes a right temperature control member 25-1, a right ear hook member 24-1, and a right fixing member 22-1. The right temperature adjusting member 25-1 adjusts the temperature of the right carotid artery of the user 68. The right ear hook member 24-1 is supported by the right ear 69 of the user 68. The right fixing member 22-1 fixes the right temperature adjusting member 25-1 to the right ear hanging member 24-1 so that the right temperature adjusting member 25-1 is held at a predetermined position with respect to the right carotid artery. . [Selection diagram] Fig. 11【課題】利用者の頸動脈の温度を適切に調節する。【解決手段】身体温冷装置の温調部１１は、右側温調部材２５－１と右耳掛け部材２４－１と右側固定部材２２－１とを備えている。右側温調部材２５－１は、利用者６８の右頸動脈の温度を調節する。右耳掛け部材２４－１は、利用者６８の右耳６９に支持される。右側固定部材２２－１は、右頸動脈に対して所定の位置に右側温調部材２５－１が保持されるように、右耳掛け部材２４－１に右側温調部材２５－１を固定する。【選択図】図１１
