PURPOSE: It makes maintain to the operating temperature by using the heat generating in the winter time outside temperature degradation with the exothermic reaction of the exothermic reactant quality, it best suited. It is polished of the wiper blade, performance can be kept with best. CONSTITUTION: A self heating type wiper blade inducing chemical reaction comprises a first heating reactive material(111), a second heating reactive material(121), a hollow unit, a temperature sensitive valve, and a form-molding unit. The first heating reactive material locates in the inner side or the outside of the wiper blade for automobile. The second heating reactive material is provided from outside. In hollow, the first heating reactive material is saved. It is formed so that the second heating reactive material is provided to the inner side. In hollow, when in the route that the second heating reactive material penetrates into the inner side below set temperature, the temperature sensitive valve opens so that the second exothermic reactant quality be provided. In the expansion molding part, the first heating reactive material locates. The second heating reactive material is formed in order to enter into the inner side.
