PROBLEM TO BE SOLVED: To provide a method for manufacturing tubular single crystal zinc oxide whiskers which are excellent in electron mobility or light emission intensity in comparison with conventional polycrystalline zinc oxide. SOLUTION: The method for manufacturing tubular single crystal zinc oxide whiskers comprizes heating a zinc sulfide powder and an activated carbon powder at 1,100-1,200°C in a gaseous argon stream for 2-4 h, and heating them at 1,100-1,200°C for 1-3 h after switching from the gaseous argon to gaseous oxygen. By this method, a single crystal of zinc oxide is obtained although only polycrystalline bodies of zinc oxide are obtained by the conventional method. The whiskers are highly expected to be utilized in electronic devices, that is, light emitting diodes, diode laser or the like because the electron mobility or light emission intensity of the single crystal is more excellent than that of the polycrystalline bodies.
