Abstract

Provided is a composition for a gas seal member that can form a gas seal member capable of sufficiently suppressing both the occurrence of overflow fracture and the occurrence of blister fracture. The disclosed composition for a gas seal member is a composition for a gas seal member that contains an elastomer and a fibrous carbon nanostructure. The fibrous carbon nanostructure includes single-walled carbon nanotubes and the fibrous carbon nanostructure is contained in a proportion of at least 0.1 parts by mass and no greater than 12 parts by mass per 100 parts by mass of elastomer.
