Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of a light emitting tube by which, the light emitting tube can be integrally molded, and breaking of a narrow tube part of the light emitting tube can be restrained, and to provide a core used for the same. SOLUTION: For the manufacture of the light emitting tube composed of a main tube part as a discharging space and a narrow tube part housing electrodes, a core 6 is formed inside a light emitting tube forming mold (7, 8), and afterwards, slurry 12 is injected. At the core 6, an axial body 3 is formed at the part forming an inner shape of the narrow tube part of the light emitting tube.
