PROBLEM TO BE SOLVED: To provide a fireproof treatment tool capable of easily forming a fireproof treatment structure without requiring a lot of thermal expansion refractory material and to provide a fireproof treatment structure.SOLUTION: A fireproof treatment tool 11 includes: a substrate 12 made of a nonflammable material formed into such a size as to close an entire through-hole of a wall W. At the substrate 12, insertion holes 16 in which a plurality of conduits D are to be inserted are formed by being mutually separated. At a rear face of the substrate 12, first and second thermal-expansion fireproof sheets 15, 19 are integrally provided and each of the insertion holes 16 is surrounded by thermal expansion refractory materials such as the first and second thermal-expansion fireproof sheets 15, 19. |
