Abstract
A flexible tube for endoscope comprising a helical tube, a net tube put on the helical tube, an outer skin put on an outer peripheral surface of the net tube, and a topcoat put on a surface of the outer skin. The outer skin and the topcoat are molded substantially simultaneously or successively by the two-coat molding method.
