<P>PROBLEM TO BE SOLVED: To provide a flat electrode which is used for forming an electric field in an electric dust collecting apparatus, between two of which the occurrence of creeping discharge is restrained and which contributes to the improvement of the uneven intensity of the formed electric field. Ž<P>SOLUTION: The flat electrode (7) includes: an electric insulator (17) consisting of sheet pieces; a first electrically-conductive part (19) formed on one surface of the electric insulator; and a second electrically-conductive part (21) connected to the first electrically-conductive part. The first electrically-conductive part consists of a belt-like stripe extending from one part of the periphery of the electric insulator toward the other part thereof. The second electrically-conductive part is composed of a plurality of wire-like stripes (41) each having the electrical resistivity higher than that of the belt-like stripe and made to exist in a virtual closed curve (43) extending along the periphery of the electric insulator while being spaced from the periphery.
