PROBLEM TO BE SOLVED: To provide a vacuum cleaner hose having excellent integration strength between conductive wires and a hose wall to be integrated with a vacuum cleaner hose.SOLUTION: A vacuum cleaner hose 2 is configured by spirally integrating resin-coated conductive wires 4 and 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 the inner layer 42. The hose wall 3 is formed with spiral recessed grooves, and the outer layer 43 and the hose wall 3 are joined and integrated in a state that parts of the resin conductive wires 4 are stored in the recessed grooves. A synthetic resin constituting the outer layer 43 is a softer synthetic resin than a synthetic resin constituting the inner layer 42, and fixing strength between the inner layer 42 and the outer layer 43 is set weaker than joining strength between the outer layer and the hose wall. |
