[Solution] A masterbatch containing an amorphous resin (A) and a chain extender (B) having a weight-average epoxy functional group count of 2 to 70 and a weight-average molecular weight of 100 to 100,000. The content of the chain extender (B) in the masterbatch is 2% to 34% by mass based on the total mass of the masterbatch, and it is a masterbatch for sealing members.
