PURPOSE: Provided is a corrugated conduit tube capable of attaining sufficient mechanical properties and flame resistance, which requires minimum or no use of halogen based flame retardant and phosphorus based flame retardant. CONSTITUTION: A corrugated conduit tube is characteristically formed of a tubular resin composition having a rough surface, and protects a conduit inserted therein. The resin composition contains the resin component 100 pts.wt. containing high density polyethylene of 75-99 wt.% and at least one type of the following group of 25-1 wt.%: ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, ethylene-(meta)acrylic acid copolymer, and surface-treated metal hydroxide of 3-39 pts.wt.
