PROBLEM TO BE SOLVED: To provide a pipe closing member capable of preventing dew condensation water generated on a building surface material from immersing into a heat insulation layer along the pipe closing member even if a pipe closing member is used against a pipe having a heat insulation layer made of glass wool at its outer circumferential part.SOLUTION: This invention relates to a pipe closing member for tightly closing a clearance between a pipe passing through a construction face material and the construction face material. This pipe closing member comprises a seal part that is a flexible plate-like segment and has an open hole into which the pipe passes; and a base part for fixing the seal part to the construction face material. The seal part has a back board protruded and arranged to enclose the open hole at one face of a peripheral edge part of the open hole, the peripheral edge portion of the open hole is deformed to protrude like a tubular form along an outer circumferential surface of the pipe, and thereby a diameter of the open hole can be increased in compliance with the outer diameter of the pipe. |
