Even if the conventional cooling/heating means described above are applicable to specific places such as homes, they cannot immediately change the color of the thermochromic layer of the object whenever and wherever necessary, and the discoloration point occurs in the low temperature range. It was not possible to effectively express the function of the thermochromic element. Furthermore, the application of the above-mentioned cooling/heating medium has a limit on the duration of cooling, and requires the troublesome effort of preparing the medium each time. In addition, in the case of non-water resistant thermochromic elements, not only direct contact with the cooling medium, but also indirect contact operations in which the cooling medium is housed in the container and applied, will cause the formation of heat discoloration on the surface of the container. The thermochromic element tends to deteriorate due to a layer of condensation, water droplets, or water leakage.

The energized heating element 7 self-generates heat and rises in temperature, the resistance value rapidly increases accordingly, the temperature rise becomes low, and the self-temperature is stably controlled at a temperature where the amount of heat generated and the amount of heat dissipated match. Looking at the relationship between the elapsed time after energization and the heat generation temperature, it is found that the metal heating element system has an extremely small rate of change in resistance due to temperature, so the amount of heat generated per unit time due to temperature rise is approximately constant, and the temperature increases. In contrast, in the energized heating element 7 of the present invention, a large current flows immediately after energization, and the temperature rises rapidly to a predetermined temperature at a large rate.

On the other hand, in the case of a metal heating element system, the stable temperature is about 32°C when the ambient temperature is 20°C, and the stable temperature is about 28°C, because the change in calorific value per unit time due to temperature is small. As shown by the experimental data of a stable temperature of 39°C and a difference of 7°C, the current-carrying heating element 7 applied to the present invention is
