    摘要： The present invention is to provide hollow particles with a low degree of agglomeration and having a high roundness, and a process for producing them.Hollow particles comprising a silicon compound, having an average particle size of from 5 to 65 nm and an average roundness of at least 0.90, and having a shell comprising the silicon compound and having a thickness of from 1 to 20 nm. Further, a method for producing hollow particles, which comprises adding sulfuric acid to a liquid containing spherical organic polymer-silicon compound composite particles having a core comprising an organic polymer and a shell comprising a silicon compound in a medium containing at least 95 mass % of water, followed by heating to carbonize the organic polymer thereby to convert it to a carbide, and subjecting the carbide to decomposition using a liquid oxidizing agent other than sulfuric acid.
