摘要：
A dental curable composition which comprises a radically polymerizable monomer component (A), a polymerizing catalyst (B) and an inorganic granular material (C), characterized in that:the radically polymerizable monomer component (A) contains a bifunctional monomer (A-1) represented by the following formula (α),RP—；SP1—；RP ； ；(α)where, RP is a radically polymerizable group represented by CH2═；C(R)—；COO—； or CH2═；C(R)—；CONH—；, wherein R is a hydrogen atom or a hydrocarbon group having 1 to 3 carbon atoms, and SP1 is a hydrocarbon group having 5 to 15 carbon atoms,and the content of the bifunctional monomer (A-1) in the radically polymerizable monomer component (A) is 5 to 40% by mass under a condition that the content of a diluting monomer (A-2) represented by the following formula (β),RP—；SP2—；RP ； ；(β)where, RP is as defined in the above formula (α), and SP2 is an aliphatic hydrocarbon group different from. SP1, an oxygen-containing aliphatic hydrocarbon group having not less than 2 oxygen atoms, or an oxygen-containing aromatic hydrocarbon group having not less than 3 oxygen atoms,is zero or not more than 10% by mass.
