PROBLEM TO BE SOLVED: To provide a method for producing a non-staining photocurable resin for electronic parts, which can efficiently promote a urethane reaction in a urethanizing process; to provide a photocurable resin for electronic parts, obtained by the production method; and to provide a sealant for electronic parts, using the same. SOLUTION: There are provided the method for producing the photocurable resin for the electronic parts, including a reaction process for reacting a conjugated diene-based polymer polyol or a conjugated diene-aromatic vinyl-based copolymer polyol with a photocurable unsaturated hydrocarbon group-containing compound in the presence of a titanium-based catalyst, wherein the ratio (X:Y) of the hydroxyl group equivalent (X) of the polyol in the conjugated diene-based polymer polyol or the conjugated diene-aromatic vinyl-based copolymer polyol to the photocurable unsaturated hydrocarbon group-containing compound equivalent (Y) is 1:1.5 to 1:2.5; the photocurable resin for the electronic parts, obtained by the production method; and the sealant for electronic parts, prepared by curing the photocurable resin.
