A calcium phosphate cement or the like which shows a low viscosity and excellent handleability in the step of kneading and achieves a high strength of the hardened body even though a kneading liquid is used in a small amount. A calcium phosphate cement containing a polysaccharide powder and 0.05 to 5% by weight of an N-alkyl-D-glucamine such as N-methyl-D-glucamine; or a calcium phosphate cement containing a calcium phosphate powder and a specific alkanolamine such as monoethanolamine. A calcium phosphate cement composition containing a calcium phosphate powder and a kneading liquid comprising an aqueous solution containing 0.1 to 10% by weight of an N-alkyl-D-glucamine such as N-methyl-D-glucamine or a kneading liquid containing a definite amount of a specific alkanolamine such as monoethanolamine.
