Summary:A hollow tubular body for molten glass by which local-overheating in the electrode for conduction heating is prevented. A hollow tubular body for molten glass by which local-overheating in the electrode for conduction heating is prevented. A hollow tubular body having a platinum or platinum alloy hollow tube, used for conduction heating is characterized in that a ring electrode is joined to the outer circumference of the hollow tube, at least one lead-out electrode is joined to an outer edge of the ring electrode, and the ring electrode comprises a core portion of electrode of platinum or platinum alloy and a thick portion of platinum or platinum alloy or of a metallic material other than platinum or platinum alloy, provided at an outer side of the core portion of electrode.
