  To provide an inkjet ink which can reduce an aldehyde-derived odor of a cured film and suppress the migration amount. The present invention is an active ray curable inkjet ink including: a radical polymerizable compound; a radical polymerization initiator; a color material; and an odor material scavenger. The radical polymerization initiator produces aldehyde by irradiation with active rays. The radical polymerizable compound contains a monofunctional radical polymerizable compound in an amount of 0 mass% to 10 mass% with respect to the total mass of the ink. The odor material scavenger is a compound having a primary amine group or secondary amine group in a molecule and having a molecular weight of 1000 or less, or is a compound having a hydroxyl group where α-position carbon is primary carbon or a compound having an aromatic ring-substituted hydroxyl group and having a molecular weight of 1000 or less. The content of the odor material scavenger is lower than the content of the radical polymerization initiator. Furthermore, the absorbance of the inkjet ink to light having a wavelength of 365 nm to 395 nm is 400 to 1000.
