Abstract
Provided are composite particles which exhibit excellent fluidity and high liquid retentivity and which exhibit high fluidity even in a liquid-holding sate. Also provided are composite particles which permit direct compressing in an open feed manner and which suffer from little compressing trouble and exhibit high shapability. When shaped together with an active ingredient, the composite particles provide shaped bodies which have uniform weight, uniform active ingredient content, and high hardness and which suffer from less galling.
