A flexible composite hose comprises an inner tube formed from a synthetic resin, an outer tube formed from a thermally shrinkable synthetic resin, having a relatively small wall thickness and carrying an adhesive on its inner peripheral surface, and a metal wire interposed spirally between the inner and outer tubes. The adhesive and the thermal shrinkage of the thermally shrinkable resin cause the inner peripheral surface of the outer tube to stick closely to the inner tube and the wire. The outer tube has a spirally corrugated outer peripheral surface defined by the wire.
