Key statement: Disclosed is a sealing material formed of a powdered material into which a rubber base sealing material with a viscosity of 20 to 200 Pas/100[degrees]C is pulverized at a temperature lower than, or equal to, a brittle temperature of the rubber base sealing material, and a method of applying the sealing material, which includes applying the powdered material to a surface to be coated with the powdered material, by a spray coating process.
