PROBLEM TO BE SOLVED: To provide a sealing method for stable continuous sealing with a prescribed sealing force, when sealing a sealant by heat. SOLUTION: In a sealing method for sealing a sealant by the application of heat with rubber plate, a rubber plate is cooled by applying air to the rubber plate in advance, thereby preventing fluctuations of sealing forces which are due to the variance of the surface temperature of the rubber plate. |
