摘要：
A bone cement composition which contains large-diameter (meth)acrylate polymer particles having an average particle diameter of 10 to 60 μm, small-diameter (meth)acrylate polymer particles having an average particle diameter of 0.1 to 2.0 μm, a (meth)acrylate monomer and a polymerization initiator, wherein the content of the small-diameter (meth)acrylate polymer particles is 5 to 30% by mass based on the total mass of the small-diameter (meth)acrylate polymer particles and the large-diameter (meth)acrylate polymer particles, and a part or a whole of the small-diameter (meth)acrylate polymer particles are contained in the form of aggregates having an average particle diameter of 30 to 50 μm.
