Provided are an epoxy ester resin and a vinyl-modified epoxy ester resin capable of obtaining a resin composition in which a pigment is sufficiently dispersed even when a pigment having low dispersibility is used, and forming a coating film having excellent gloss. An epoxy ester resin having a polymerizable unsaturated group and a condensed alicyclic structure, and a vinyl-modified epoxy ester resin having a condensed alicyclic structure containing the epoxy ester resin and a polymerizable monomer as reaction components, in which a mass ratio [(epoxy ester resin):(polymerizable monomer)] of the epoxy ester resin having a polymerizable unsaturated group and a condensed alicyclic structure to the polymerizable monomer is in a range of 20:80 to 80:20.
