Zusammenfassung:	PROBLEM TO BE SOLVED: To make thin the thickness of a pipe wall inside a thermal expansion material, and to quickly close a penetration hole by embedding the thermal expansion material into the pipe wall of a fireproof compartment penetration joint.SOLUTION: The fireproof compartment penetration joint 10 includes the pipe wall formed by being integrated with a synthetic resin in a melt state by injection molding, and the thermal expansion material 20 embedded into the pipe wall at a position corresponding to the penetration hole 22. A fireproof compartment penetration conduit 30 constituting a drain conduit which penetrates the penetration hole 22 of a fireproof compartment 14 is constituted by connecting pipes 16 by the fireproof compartment penetration joint 10.
