A method of producing a carbon material-containing material having a precisely controlled structure under a mild condition, a carbon material-containing material covalently bonded to an inorganic matter, and an intermediate material which is useful for, for example, industrially producing carbon-coated inorganic particles, hollow carbon fine particles, and can be industrially produced under a mild condition, are provided. The method of producing a carbon material-containing material includes heating a composition containing a compound (A), which causes a condensation reaction between the same and/or different molecules, and an inorganic matter. When the compound (A) has a condensation reaction temperature of T° C., a heating temperature is (T-150)° C. or more. The carbon material-containing material includes a carbon material and an inorganic matter. At least part of the carbon material and inorganic matter are covalently bonded. The organic-inorganic composite includes a carbon material and an inorganic matter. The carbon material is soluble in a solvent.
