A conveyance roller for a heating furnace includes: a roller body constituted by a metal tube made of a heat-resistant alloy; at least one holding protrusion provided on an outer circumferential surface of the roller body for holding an object to be heated in the heating furnace, and protruding from the outer circumferential surface of the roller body in a plurality of positions at a given interval in a longitudinal direction of the roller body; and at least one shielding member provided to be adjacent to the at least one the holding protrusion in the longitudinal direction, and covering the outer circumferential surface of the roller body. The at least one shielding member has a thickness not larger than a height of the holding protrusion from the outer circumferential surface of the roller body.
