PROBLEM TO BE SOLVED: To notify a vacuum cleaner user of an occurrence of abrasion and damage of a conductive wire by facilitating detection of the abrasion and damage of the conductive wire of the hose for the vacuum cleaner.SOLUTION: A vacuum cleaner hose 2 is configured by spirally integrating resin-coated conductive wires 4 with a hose wall 3 formed of synthetic resin into a substantially cylindrical shape. The resin-coated conductive wire 4 that is covered by a multilayer structure includes: a wire rod 41 having conductivity; a synthetic-resin insulation layer 42 for covering the wire rod 41; and a synthetic-resin colored layer 43 for covering further outside of the insulation layer 42. The insulation layer 42 and the colored layer 43 are formed of mutually different-color resin materials. |
