Abstract
A flexible hose which is formed by attaching a resin reinforcing coil member to a cylindrical body, the cylindrical body being composed of a nonwoven fabric layer which is formed by winding a nonwoven fabric tape spirally and connecting adjacent side end portions and an air-cut layer which forms on at least one side of the nonwoven layer. The nonwoven fabric tape and the reinforcing coil member are formed of heat-fusible resin materials, and the reinforcing coil member is fused with the nonwoven fabric layer in a body.
