PROBLEM TO BE SOLVED: To suppress a decrease in manufacturing efficiency and an increase in cost by simplifying a structure for holding a predetermined solution in a nonuse state and a supercooled state and a crystallization starting part.SOLUTION: In a heating implement 100 for eyes, the crystallization starting part P for starting crystallization of the predetermined solution by coming into contact with the predetermined solution is attached in such a manner as to adjoin the opposite side of a first accommodation part 11 of one of parts where first and second packaging members are stuck on each other, to an inner surface of one of the first and second packaging members 1A and 1B of a body part 1 housing the predetermined solution L in the supercooled state, generating heat by phase transition. One of the parts where the first and second packaging members are stuck on each other partitions the first accommodation part and the crystallization starting part in the nonuse state of the heating implement, and is separated by pressure, which is applied from at least one of the side of the first accommodation part and the side of the crystallization starting part in use, so that the inside of the first accommodation part and a space where the crystallization starting part is present can communicate with each other.COPYRIGHT: (C)2013,JPO&INPIT【課題】非使用状態で過冷却状態の所定の溶液と結晶化開始部とを保持する構造を簡略化して、製造効率の低下やコストアップを抑制する。【解決手段】目用温熱具100であって、相転移により発熱する過冷却状態の所定の溶液Lが収容された本体部1の第1及び第2包装部材1A、1Bのうち、一方の包装部材の内面に、第1及び第2包装部材が貼り合わされる部分における一部分の第1収容部11と反対側に隣り合うように、所定の溶液と接することで当該所定の溶液の結晶化を開始させる結晶化開始部Pが付着され、第1及び第2包装部材が貼り合わされた部分における一部分は、当該温熱具の非使用状態にて第1収容部と結晶化開始部とを仕切るとともに、使用の際に第1収容部側や結晶化開始部側のうちの少なくとも一方から加えられる圧力により剥がされて当該第1収容部の内側と結晶化開始部の存する空間とを連通させる。【選択図】図1
