PROBLEM TO BE SOLVED: To provide a temperature abnormality warning method of a plug capable of executing accident prevention by avoiding danger such as ignition of a wire by covering a plug surface with temperature-sensitive discoloration ink to cause discoloration in the temperature-sensitive discoloration ink to form warning action when the working temperature of the plug is set abnormally high. SOLUTION: A heat transfer unit is selected. A surface of the heat transfer unit is covered with the temperature-sensitive discoloration ink. The heat transfer unit is coupled to a position capable of receiving the plug working temperature on the plug. The temperature-sensitive discoloration ink receives the plug working temperature through the heat transfer unit, and warns of the temperature abnormality of the plug by using a phenomenon causing the discoloration based on the temperature.
