ABSTRACT:
In a method of measuring particles floating in an atmosphere, the atmosphere containing the particles is sucked into a container, ions are generated from a discharge electrode disposed in the container to charge the particles with the ions. A dust-collecting electrode is arranged in the container to electrically conduct with a ground potential, wherein the dust collecting electrode is formed of a transparent plate having a transparent conductive film on a surface thereof facing the discharge electrode. The charged particles are collected on the dust-collecting electrode disposed in the container by using a potential difference relative to the discharge electrode, and the particles on the dust-collecting electrode are measured.
