[0001]

The present invention relates to an electrothermal device having flexibility and air permeability, which has various advantages such as difficulty in tearing, sufficient ventilation, high durability, and comfortable feeling.

Humans have devised many heating devices to keep the temperature higher than the surrounding environment to heat or insulate the body and all fluids or objects. For example, there are electric mats, electric battens, foot muffs, and heated blanket, all of which are electrothermal products for melting in the winter. And a heating electric resistance circuit in which one pair or a plurality of pairs of heat transfer members are provided in the middle of the two blankets or the layers of the faces. The electric energy of the heat transfer member is converted into thermal energy at the time of energization so that the surface temperature of the articles such as the heat transfer mat, the heat transfer bum, the heat transfer bum, and the heat blanket becomes higher than the ambient temperature, , Or a user who wears a thermal jacket or an electric heating jacket.
