PURPOSE: An anion-generating apparatus is provided, which generates the anions at a lower voltage because of making a tip having a low curvature, and increases the number of anions generated per unit area substantially because of the high density of tip, by using a carbon nano-tube tip as an anode tip. CONSTITUTION: The anion-generating apparatus is characterized by using the carbon nano-tube tip as an anode material. The forming method of the carbon nano-tube tip includes the step of growing the carbon nano-tube on a metal film formed on a substrate by a chemical vapor deposition. The anion-generating apparatus is characterized in that the carbon nano-tube tip is used as an anode, a metal is used as a cathode, the anions are generated by applying voltage in the two electrodes to discharge, and the dusts bonded to the anion are collected in the cathode. |
