To provide a photopolymerizable inkjet ink made as excellent in long term stability and curing property, and having a firm film strength and a low curing shrinkage even having low viscosity.

This photopolymerizable inkjet ink containing a photopolymerizable resin consisting only of photopolymerizable monomers, photopolymerization initiator and coloring agent, and not containing a solvent, wherein, the photopolymerization monomers contain 10-30 wt. % hexa-functional monomer based on the total amount of the ink, and uses any of a di-functional monomer, or the di-functional monomer with a mono-functional monomer, or the di-functional monomer with a tri-functional monomer, or the mono-functional monomer with the di-functional monomer and the tri-functional monomer, as the photopolymerizable monomers other than the hexa-functional monomer.
