PROBLEM TO BE SOLVED: To provide a fluorescent display tube with a positive electrode pattern with an inter-electrode space of 100μm or less in photolithography. SOLUTION: Of the fluorescent display tube with a positive electrode layer pattern-formed by the photolithography method, the positive electrode layer is a calcined body of granular conductive metal powder and frit glass powder, with an average particle size of the former and the latter of 1 to 30μm, each, and the former being granular aluminum metal powder.
