PROBLEM TO BE SOLVED : To provide an active energy ray-curable inkjet ink composition having good storage stability.SOLUTION : The active energy ray-curable inkjet ink composition contains a compound (A) represented by the following formula, a radically polymerizable monofunctional monomer (B) having an SP value of 9.6 or less, a radically polymerizable monofunctional monomer (C) having an SP value of 10.0 or more, a photopolymerization initiator (D), and a pigment (E). The total content of (B) and (C) in a radically polymerizable component is 40-90 mass%, and the content of (A) is 0.1-2.0 mass%. (x is 0 or 1; Rto Rare each H or an alkyl group; and Ris a 1-10C organic group.)
