    • PURPOSE: A manufacturing method of spherical microcup particles of a calcium phosphate compound is provided to manufacture the spherical microcup particles of the calcium phosphate compound by adding and mixing polyvinyl pyrrolidone to a sol-gel precursor including calcium and a phosphate salt and then electrospraying and heat-treating the mixture. CONSTITUTION: A manufacturing method of spherical microcup particles of a calcium phosphate compound comprises steps of: adding and mixing polyvinyl pyrrolidone to a sol-gel precursor including calcium and a phosphate salt, electrospraying the mixture, and performing heat-treatment on the resultant. A molar ratio of the calcium and phosphate salt is from 1.0 to 2.0. An additive content of the polyvinyl pyrrolidone is from 0.1 to 5 weight% of the whole mixture.
