A flexible tube for an endoscope includes a flexible tube base, an outer coating layer including a soft resin layer and a hard resin layer, a ratio changing portion, and a tapered portion. In the ratio changing portion, a percentage of a thickness of the hard resin layer decreases and a percentage of a thickness of the soft resin layer increases toward a distal side from a proximal side of the base. In the tapered portion, a ratio between the thickness of the hard resin layer and the thickness of the soft resin layer is maintained, which ratio is the same as that at a position in the ratio changing portion where the percentage of the thickness of the hard resin layer is a lower limit. In the tapered position, an outer diameter of the outer coating layer decreases toward a distal end of the flexible tube base.
