<p>Surface tackiness of a hose is improved without using a partially crosslinked resin. By heat-molding a hose while mixing a plurality of synthetic resins having different molecular weights in the surface of the hose, particles of the synthetic resins having high molecular weights remain in the molten synthetic resins having low molecular weights, thereby forming fisheyes in the hose surface. Fine projections and recesses due to the fisheyes make the hose surface into a low friction surface.</p>
