PROBLEM TO BE SOLVED: To provide a method for producing a modified-sulfur-containing material, which method can produce the modified-sulfur-containing material capable of utilizing general and industrial wastes as an aggregate therefore, excellent in mechanical properties, water barrier properties, ignition resistance, and resistance to sulfur oxidation bacteria, and useful as a civil engineering and building materials efficiently with ease of reaction control, and is suited for industrial mass-production and to provide the modified-sulfur-containing material produced thereby. SOLUTION: The method comprises the steps of: mixing and reacting molten sulfur with a sulfur modifying agent to obtain modified sulfur, cooling and keeping the modified sulfur to or at the melting temperature of the modified sulfur to 135°C or lower by a thermal diffusion means, transferring the cooled and kept modified sulfur kept in a flowable state to a batch mixer, mixing a raw material containing the flowable modified sulfur and an aggregate, and cooling and solidifying the mixed raw material.
