PROBLEM TO BE SOLVED: To provide an energy ray curable resin composition having a low dielectric constant and excellent transparency. (A) Conjugated diene polymer having two or more α, β-unsaturated carbonyl groups (α, β-unsaturated carbonyl-modified conjugated diene polymer); (B) Hydrophilic group (meth) A polymerizable component containing an acrylate compound (B1); and (C) a photopolymerization initiator. The (A) unsaturated carbonyl-modified conjugated diene polymer is a polyol (a-1) having a number average molecular weight of 500 to 20000 through one type of bond selected from the group consisting of a urethane bond, an ester bond, and an ether bond. Are linked to each other, and the molecular chain terminal of the multimeric polymer preferably includes a multimeric conjugated diene polymer in which α, β unsaturated carbonyl modification is performed.
