PROBLEM TO BE SOLVED: To provide a duct removing implement which facilitates disposal of an adhesive sheet by allowing a user to know the timing of an adhesive sheet peeling. SOLUTION: In this duct removing implement 10, an adhesive part 13 having a plurality of adhesive sheets 31 laminated thereon is arranged on a base part 13. The individual adhesive sheets 31 are made transparent to allow visual recognition of a white layer 23 arranged on the surface of the base part 12 and an indicator 25 provided on the surface of the while layer 23. Therefore, as viewed from above the adhesive part 13, the white layer 23 and the indicator 25 are observed through adhered dust. Thus, both colors are compared to allow to discriminate the amount of dust adhering to the adhesive sheet 31. A polylactate film used in the adhesive sheet 31 facilitates discarding treatment after peeling.
