Abstract
A hose capable of exhibiting increased flexibility and lubricity. The hose is made of soft synthetic resin containing a slidability providing silicone resin material. In particular, the slidability providing silicone resin material contained in a surface layer of the hose or ribs formed on a surface of the hose. In production of the hose, re-dispersion of the resin material and forcing of layers of the hose against each other are carried out. Alternatively, a layer containing the resin material and a layer free of the resin material are co-extruded.
