An object of the present disclosure is to provide an encapsulation resin in which the occurrence of cracks is suppressed when the resin is used for encapsulation of ultraviolet light-emitting elements. Another object of the present disclosure is to provide an encapsulation resin composition for supplying the encapsulation resin. The present disclosure relates to an encapsulation resin for light-emitting elements, comprising a fluoropolymer, wherein the fluoropolymer comprises, as a main component, a monomer unit represented by formula (1): wherein R1 to R4 are each independently a fluorine atom, a fluoroalkyl group, or a fluoroalkoxy group.
