A method and apparatus exists for manufacturing needle-shaped materials for use as microemitters, wherein a light beam output from a light source is split into a plurality of beams and the split light beams are focused by an optical system and directed into a chamber having a gas containing electroconductive molecules. The electroconductive molecules are degraded through excitation by the beams directed into the chamber to deposit needle-shaped materials on a substrate disposed in the chamber. By so doing, a plurality of needle-shaped materials are simultaneously produced on the substrate in accordance with a corresponding number of beams obtained through splitting.
