Abstract

To provide a dental curable composition having excellent curability and storage stability. The dental curable composition contains (a) transition metal adsorbent in which a transition metal compound of the period 4 in the periodic table is adsorbed on an inorganic particle which is non-reactive with a transition metal of the period 4 in the periodic table, (b) thiourea derivative, (c) organic peroxide having a hydroperoxide group, and (d) polymerizable monomer, wherein the (d) polymerizable monomer contains (d-1) acidic group-non-containing polymerizable monomer, and wherein a pore volume of the inorganic particle which is non-reactive with a transition metal of the period 4 in the periodic table is 0.2 cc/g or less.
