PROBLEM TO BE SOLVED: To solve the problem on a conventional corrugated pipe joint that water tightness cannot be maintained under high water pressure. SOLUTION: A corrugated pipe joint for covering and mutually connecting the pipe ends of corrugated pipes having spiral or independent ring unevennesses on peripheral walls is formed with plural pieces of cylindrical members. A sheet foamed resin is laminated on the inner periphery of the corrugated pipe joint and an nonwoven and/or woven cloth formed of water absorptive resin is laminated on the inner periphery of the foamed resin. The nonwoven and/or woven cloth is adhered to the outer periphery of a contact area between both ends of the pipes.
