Zusammenfassung:PROBLEM TO BE SOLVED: To provide a production method and a production device for a sulfur solidified body where sulfur-containing materials in a molten state are poured into a sealable molding flask heated within a set temperature range under prescribed pressure, and thereafter, the materials are cooled and solidified within the molding flask so as to mold a sulfur solidified body. SOLUTION: Sulfur-containing materials in a molten state are stored into a material hopper 1 heated within a set temperature range which is the melting point of sulfur or above, this stored sulfur-containing materials are sucked by pressure generators 2a, 2b, and are pulled out inside cylinders 11a, 11b heated within the above set temperature range, the pulled-out sulfur-containing materials are extruded from the cylinders in such a manner that prescribed pressure is applied by the pressure generators, and are poured from a pouring port 24 into a molding flask 5 having a sealable cavity at the inside and heated within the above set temperature range, the pouring port of the molding flask after the sulfur-containing materials are poured into the cavity to the limit is closed, the heating of the molding flask is stopped, the sulfur-containing materials poured into the cavity are annealed, and the sulfur-containing solidified body molded in such a manner that the sulfur-containing materials in the cavity are cooled and solidified is taken out from the molding flask.
