Zusammenfassung:	Provided are a photocurable resin composition which has a short time required for curing to make it possible to enhance the productivity and which can provide a light-emitting element sealant having an excellent heat resistance and an excellent optical transparency and a light-emitting element sealant prepared by using the above photocurable resin composition. To be specific, provided are a photocurable resin composition comprising 100 parts by mass of an end-modified hydrogenated styrene-butadiene rubber (A) and 0.1 to 13 parts by mass of an α-hydroxyalkylphenone base photopolymerization initiator and/or an acylphosphine oxide base photopolymerization initiator and a light-emitting element sealant prepared by using the above photocurable resin composition (B).
