Abstract

The present invention has an object to provide a photocurable resin composition which exhibits excellent surface curability and deep section curability when irradiated with active energy rays such as ultraviolet rays while maintaining sealability. Specifically, provided is a photocurable resin composition containing the following (A) to (C) ingredients: (A) ingredient: a polymer having a polyisobutylene backbone containing a —[CHC(CH)]— unit, the polymer having one or more (meth)acryloyl groups; (B) ingredient: a photo-radical polymerization initiator; and (C) ingredient: a triarylphosphine derivative or a xanthone derivative.
