In the present invention, the dow time, which is a time required until a state in which a good handling operation can be performed, is short, and as a result, the time required for starting a handling operation becomes short, so that a high work efficiency can be achieved. An object of the present invention is to provide a cement cement composition kit for obtaining a cement composition and a bone cement composition and a method for producing a bone cement cured product. The bone cement composition of this invention is a (meth) acrylate type polymer large diameter particle whose average particle diameter is 10-60 micrometers, (meth) acrylate type polymer small diameter particle whose average particle diameter is 0.1-2.0 micrometers, and (meth ) The acrylate monomer and a polymerization initiator are contained, and the content rate of the said (meth) acrylate type polymer small diameter particle | grains is the total amount of the said (meth) acrylate type polymer small diameter particle | grains and the (meth) acrylate type polymer large diameter particle | grains. It is characterized by being 5-30 mass% with respect to. |
