PROBLEM TO BE SOLVED: To provide a heating implement, wherein fitness for a region for wearing it is improved.SOLUTION: The heating implement 100 for eyes applies heat to the region where a wearer H wears the heating implement. A predetermined solution L in a supercooled state, which generates heat by phase transition, is housed in the body part 1 of the implement. A predetermined amount of an adjustor for adjusting the softness in the crystallized state of the predetermined solution is added to the predetermined solution.COPYRIGHT: (C)2013,JPO&INPIT【課題】着用される部位に対するフィット性を向上させた温熱具を提供する。【解決手段】着用者Hの着用された部位に温熱を付与する目用温熱具100であって、当該装置の本体部1に、相転移により発熱する過冷却状態の所定の溶液Lが収容され、所定の溶液には、当該所定の溶液が結晶化された状態での柔らかさを調整する調整剤が所定量添加されてなる。【選択図】図1
