Abstract
A fluid-impermeable composite hose has a laminated layer having a high impermeability to a refrigerant, etc. and held between two resin layers having a thickness which is small enough to enable the hose to remain flexible. The resin layers secure and protect the laminated layer and protect a metallic foil in the laminated layer from any bending, deforming or stretching force acting upon the hose.
