摘要： A method 1 for manufacturing a seal body includes a belt-like body forming step including a crosslinking agent adding step S 1 in which a crosslinking agent 3 is added to a compound 2 containing a halogen group-containing monomer as a constituent unit and mixed, a kneading step S2 for kneading the obtained mixture 4, a pressurizing step S3 for pressurizing the kneaded material 5, and a cutting step S4 for cutting the pressurized body 6 into a belt-like body 7, and a press-fixing step including a press-fixing/heating step S5 of press-fixing one end and the other end of the belt-like body 7 to form an endless seal body 8.
