The purpose of the present invention is to provide an active light ray-curable inkjet ink composition which exhibits excellent curing properties and high storage stability. This active light ray-curable inkjet ink composition contains a curable monomer, a photopolymerization initiator, an amine-modified oligomer, a pigment and a polymer dispersing agent. In this composition, the content of the amine-modified oligomer is 0.5-10 mass% relative to the overall mass of the active light ray-curable inkjet ink composition, the polymer dispersing agent is a compound which adsorbs the pigment and contains a tertiary amine group as a functional group, and the content of the polymer dispersing agent is 20-70 mass% relative to the pigment.
