The active ray-curable inkjet ink comprises a gelling agent, photopolymerizable compounds and a photoinitiator, and reversibly transitions into a sol-gel phase according to the temperature. Therein: (1) a (meth)acrylate compound having a molecular weight of 300-1,500 and having 3-14 (—CH2—CH2—O—) structural units within a molecule is included as the first photopolymerizable compound at a proportion of 30-70 mass % relative to the total mass of the ink； (2) a (meth)acrylate compound having a molecular weight of 300-1,500 and a C log P value of 4.0-7.0 is included as the second photopolymerizable compound at a proportion of 10-40 mass % relative to the total mass of the ink； and (3) the gelling agent has a total of at least 12 carbon atoms, and has a straight or branched alkyl chain including at least three carbon atoms.
