Zusammenfassung:PROBLEM TO BE SOLVED: To provide a sealing material keeping swelling ratio low against a low molecular weight organic compound, particularly a gaseous monomer. SOLUTION: The sealing material includes a fluorine-containing polymer such as PTFE, modified PTFE, PFA, and FEP, and a compound having an inhibiting action on the swelling of the polymer due to a low molecular weight organic compound, such as an organometallic compound, a sulfur-containing compound, an amine-based compound, or a metal element.
