Abstract
A carbon microrod that holds a fine object by chemically adsorbing the object on the surface to make a dynamic measurement possible. An organic substance that leaves, after firing, glassy carbon that hardly becomes graphite, such as a chlorinated vinyl chloride resin, is mixed with a fine graphite powder having an average particle size of 1 μm, and the mixture is extrusion molded with a die having a diameter of 50 μm; the molded article is fired to give a carbon microrod comprising glassy carbon and crystalline carbon.
