PROBLEM TO BE SOLVED: To provide a closing cover of a wiring/piping material penetration part, which can make rain water from an outer cylinder hard to infiltrate indoors. SOLUTION: A closing cover 4 covers a through-hole 1a into which a wiring/piping material 2 is inserted by penetrating a wall 1 facing outdoor J of a building on the outdoor J side. The closing cover 4 includes a cover part 11, an inner cylinder 12, and an outer cylinder 13. The cover part 11 has a plate 5 covering the through-hole 1a. The inner cylinder 12 protrudes to the front side from the cover part 11, into which the wiring/piping material 2 is inserted. The outer cylinder 13 protrudes from the cover part 11 to the front side to surround the inner cylinder 12, a protective tube 3 to protect the wiring/piping material 2 can be inserted between itself and the inner cylinder 12. Inside of the outer cylinder 13, an insertion control surface 15 crossing over from the outer cylinder 13 to the inner cylinder 12 is provided so that the end of the protective tube 3 may contact and control the insertion of the protective tube 3. Additionally, in the outer cylinder 13, an outlet 13b to drain water infiltrated between the inner cylinder 12 and the outer cylinder 13 is provided in a position communicating with the insertion control surface 15.
