摘要： A porous pipe having an excellent absorbing and draining function, a producing apparatus capable of producing a porous pipe at high speed and low cost, and a method of producing a porous pipe are provided. The porous pipe is a pipe formed by spirally winding a tape. The pipe is formed by a hole forming portion 13 for forming a recess or a notch or a hole in the tape 2 molded by a tape molding portion 11, and the hole forming portion 13 is located between the tape molding portion 11 and a pipe forming portion 12 so that the tape 2 is molded, holes 6 are formed, and a pipe 1 is formed continuously. The holes 6 are formed into a predetermined shape by elongating the hole 6 from a side of the pipe forming portion 12. In the pipe 1 formed thereby, a peripheral wall portion of the hole 6 is gradually thin-walled toward an outer peripheral face of the hole.
