Claims

[Scope of utility model registration request]

A temperature-sensitive magnetic material that loses its magnetism when the temperature reaches a predetermined curie point temperature, and if the temperature-sensitive material does not have the curie point temperature indicated on one side, the curie point temperature is indicated on one side. A permanent magnet is interposed between the permanent magnet and the temperature-sensitive magnetic material, and when the temperature reaches the cue point, the temperature-sensitive magnetic material or the permanent magnet is expanded. A temperature indicator consisting of a sexual substance.
