Curable resin composition, fuel cell using same, and sealing method using same

Abstract

The present invention aims to provide a curable resin composition from which a cured product having high tensile strength and high extensibility can be obtained. A resin composition includes the following ingredients (A) to (C): ingredient (A): a polymer which has one or more (meth)acryloyl groups and has a polyisobutylene skeleton containing a —[CH2C(CH3)2]— unit; ingredient (B): a radical polymerization initiator; and ingredient (C): a monomer (c1) which has an alicyclic structure containing a (meth)acryloyl group and a substituent of a hydrocarbon group having 2 to 20 carbon atoms or a monomer (c2) which has a (meth)acryloyl group and a dicyclopentenyl group or adamantyl group.
