Claims (1)

[Scope of Claim for Utility Model Registration] (1) A dust collection device consisting of a discharge section that performs corona discharge and a dust collection section composed of a filter is disposed upstream of an air flow path in which a fan is installed, and In this section, protrusions are formed at multiple locations on a discharge electrode member made of a conductive material having strength, and the protrusions are bent to hold and fix the discharge wire, or the protrusions are wrapped around the protrusions and stretched to prevent discharge. An air purifier that is placed oppositely between opposite electrodes. (2) For the discharge part, the discharge wire is formed in a continuous U-shaped uneven pattern, sandwiched between upper and lower electrode holding plates made of a conductive material, and after being integrated with both holding plates, the U-shaped part is cut to form a needle. 2. The air cleaner according to claim 1, wherein shaped electrodes are formed and disposed facing each other between discharge counter electrodes.
