PURPOSE: To provide a reversible temperature indicating material without limitation in using states, which acts on the temperatures in a broad range and can record and indicate the temperature.
CONSTITUTION: This is the reversible temperature indicating material, wherein a temperature indication layer formed by dispersing an organic low-molecular material into an organic high-molecular resin in a particulate state is provided on a supporting body. The above described organic low-molecular material is a material, wherein at least one kind of compound containing a long-chain alkyl group whose melting point is 50-100°C and at least one kind of compound containing an alkyl group whose melting point is 100-160°C are mixed at the rate of 98:2-50:50.
