Abstract
The specification discloses a film-shaped dust collecting electrode and an electric dust collecting apparatus having a stack of the electrodes. The electrode includes a conductive film painted onto a central area of a surface of a rectangular insulative film. A terminal base and a terminal conductor of a tongue shape extend from one shorter edge of the insulative film. A plurality of spacer protrusions are provided at spaced intervals along the opposite longer edges of the insulative film. The spacer protrusions along the opposite longer edges are staggered from one another with the conductive film intervening therebetween. Hollow frustoconical coupling protrusions are disposed symmetrically about the intersection of the two diagonal lines of the insulative film. The height of the coupling protrusions is higher than that of the spacer protrusions. In the dust-collecting apparatus, a plurality of the electrodes is stacked with the direction of terminal conductors alternately reversed. The coupling protrusions prevent relative displacement between adjacent electrodes.
