2. Description of the Related Art For example, vulcanization of a large composite rubber body having a small thermal conductivity such as a seismic isolation bearing in which a plate-like rubber body and a reinforcing body are laminated is performed by heating with externally heated air or steam. It is common practice to vulcanize the rubber body by performing vulcanization (for example, JP-A-4-140526). In recent years, a method of vulcanizing by high-frequency heating or electromagnetic induction heating with a conductor interposed has been proposed (for example, Japanese Patent Application Laid-Open No. H10-244547).
