Zusammenfassung:	PROBLEM TO BE SOLVED: To cast a two-component mixing type anaerobic resin (polycyclopentadiene resin) exactly and correctly. SOLUTION: In a casting method, a molding mold and a two-component mixer are arranged in vacuum chambers 11 and 15, while the chambers are evacuated approximately completely, two liquid raw materials are mixed by the mixer to prepare the liquid anaerobic resin, and the resin is cast into the molding mold 40 and cured. A casting apparatus is composed of a vacuum casing machine 1 having the vacuum chambers which can be evacuated approximately completely, the two-component mixer which is arranged in the chamber and mixes the liquid raw materials, and an injection device which injects the liquid resin prepared by mixing the liquid raw materials into a casting mold arranged in the chamber while the vacuum is kept.
