PROBLEM TO BE SOLVED: To further ensure insulation of conductive wires for a vacuum cleaner hose.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 inner layer 42 for covering the wire rod 41; and a synthetic-resin outer layer 43 for covering further outside of the inner layer 42. A synthetic resin constituting the inner layer 42 is a softer insulation synthetic resin than a synthetic resin constituting the outer layer 42. |
