摘要

A slit forming part can be easily formed on a parting surface of a split mold and a change in a slit vent formed by the slit forming part can be suppressed. Parting surfaces (21)(22) including slit forming parts (23) are formed on the split mold (20). Plating is applied to the parting surfaces (21) (22) of the split mold (20) so as to coat the parting surfaces (21)(22) in which the slit forming part (23) is formed, with a plating film (40). A plurality of split molds (20) are combined together such that their parting surfaces (21) (22) opposed to each other, to mold a rubber article. The slit forming parts (23) of the parting surfaces (21) (22) form a slit vent (30) between the split molds (20).
