A photocuring denture base lining material is disclosed, comprising: a powder component comprising a methacrylic acid ester polymer powder and/or a methacrylic acid ester polymer powder having from 0.01 to 5% by weight of a photocuring catalyst compounded therewith; and a liquid component comprising (a) from 10 to 40% by weight of benzyl methacrylate, (b) from 20 to 40% by weight of at least one of compounds represented by the following structural formula (1): <IMAGE> (1) wherein R represents an alkyl group, (c) from 20 to 70% by weight of at least one of methacrylic acid esters having two or three methacryloyl groups in one molecule, and (d) from 0.01 to 5% by weight of a photocuring catalyst. The photocuring denture base lining material of the invention is extremely low in the unpleasant odors and irritation, is superior in the fitness and the operability, and has a high surface hardness after curing.
