Disclosed is a composition for hard tissue repair, which is characterized by containing 5-98.95 parts by weight of a monomer (A), 1-75 parts by weight of a (meth)acrylate polymer (B), and 0.05-20 parts by weight of a polymerization initiator composition (C) that contains an organic boron compound (c1) (with the total of the components (A), (B) and (C) being 100 parts by weight). The composition generates little heat when cured, and is capable of assuring sufficient working time. |
