TEMPERATURE MANAGEMENT MEMBER UNDER REDUCED-PRESSURE ATMOSPHERE, AND TEMPERATURE MANAGEMENT METHOD UNDER REDUCED-PRESSURE ATMOSPHERE

摘要

A temperature management member under a reduced-pressure atmosphere, wherein the difference in the discoloration temperature of a temperature-sensitive discoloration layer between under an atmospheric pressure atmosphere and under a reduced-pressure atmosphere can be minimized as much as possible, is provided. A temperature management member under a reduced-pressure atmosphere comprises; a temperature-sensitive discoloration layer (12) which contains granular or powdery hot-melt matter (22) that melts at a melting temperature corresponding to a heating temperature to be detected under a reduced-pressure atmosphere and which is discolored in response to the hot melting thereof, and a difference in the melting temperature of the hot-melt matter (22) within the temperature-sensitive discoloration layer (12) between under an atmospheric pressure atmosphere and under the reduced-pressure atmosphere is 5°C at most.
