PROBLEM TO BE SOLVED: To provide a cold insulation tool capable of reliably cooling a human body or a dead body without using a large scale tool or device in particular.SOLUTION: A cold insulation tool 1 for cooling a human body or a dead body comprises a first sheet 2 made of a metal thin film having high thermal conductivity and a second sheet 3 having thermal conductivity lower than that of the first sheet 2. The first sheet 2 and the second sheet 3 are placed on each other, one side of it being made to be an opening 4 and the other three sides being sealed to have the shape of a bag.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】特に大がかりな器具や装置を用いることなく、人体をまたは遺体を確実に冷やすことができる保冷具を提供する。【解決手段】人体または遺体を冷やす保冷具１を、熱伝導性の高い金属薄膜からなる第１シート２と、上記第１シート２より熱伝導率の低い第２シート３とで構成し、上記第１シート２と上記第２シート３とを重ね合わせ、その一辺を開口部４とし、他の三辺をシールして袋状とした。【選択図】図３
