To provide a heating roll of steam-type, capable of achieving uniformity of the surface temperature thereon so that a heating roll unit equipped with the roll can suitably produce such a fabric at a low cost that has neither pressurizing unevenness nor drying unevenness.

This heating roll is used in the heating roll unit through which the fabric, web or paper is passed to be thermally treated, wherein the heating roll utilizes high-pressure steam as a heat source, and both sides of the roll each have a steam-inlet for leading the steam into the roll.
