To provide a gas lamp mantle manufacturing method by which a gas lamp mantle can be manufactured with high production efficiency at low costs, which emits emerald green or pink gas color light, has high strength, and has comparatively little contraction when burnt.
A mesh carrier is dipped in luminescence component-dissolved material solution 2 and dried 3 so as to form an intermediate supporting the luminescence component in the mesh carrier. The intermediate is fixed to a seating 4 so as to form a mantle body, and thereafter, the mantle body is fitted to a gas lamp 5, and is burnt by the flame of the gas lamp 6. Erbium or thulium is used as the luminescence component, and both luminescence components of 0.1 to 1.0 mole/liter are contained in the material solution.
