PROBLEM TO BE SOLVED: To obtain a coolant having a long cooling time and a large cooling lasting effect without excess cooling such as a frostbite, or the like. SOLUTION: This coolant comprises a resin component and a volatile component. When the coolant is injected to a member to be cooled, a resin film is spread on the member. Simultaneously, the volatile component is volatilized from a surface and/or an interior of the film. The coolant cools the member by a latent heat of vaporization in the case of volatilizing the volatile component. The coolant can be used by sealing the coolant in an aerosol container. Thus, the volatile component used also as an aerosol propellant and the resin component are injected from the container. When the volatile component and the resin component are injected to the member, the volatile component such as the propellant, or the like, is volatilized. The coolant can cool the member by the latent heat of vaporization in the case of volatilizing the volatile component. |
