An object of the present invention is to provide a temperature detection material which can be produced in a simple process and is excellent in operability. In order to solve the above-mentioned problem, the temperature detection material of the present invention is characterized by comprising: a temperature display material containing a leuco dye, a color developer and a decolorizer, and a matrix material, wherein the matrix material is in a solid state, and the melting point of the matrix material is higher than that of the temperature display material. The melting point is high, forming a phase-separated structure in which the temperature-indicating material is dispersed in the matrix material. |
