An object of the present invention is to provide a polyphenol-containing solid composition that enables efficient ingestion of a polyphenol. This object can be achieved by a solid composition containing (1) an amorphous poorly water-soluble polyphenol, (2) a hydrophilic polymer, and (3) at least one nonionic surfactant selected from the group consisting of polyglycerol fatty acid esters, sucrose fatty acid esters, and lecithins.
