PROBLEM TO BE SOLVED: To provide an electric dust collector which is reduced in weight while maintaining a dust collecting function, suppressed in generation of spark discharge and prevents abnormal rise in temperature. SOLUTION: At least one among a grounded electrode plate 13 of an electrifying part 11, a charged electrode plate 22 of a dust collecting part 21 and a grounded electrode plate 23 of the dust collecting part 21 is constituted of a three-layer film 31 formed by holding an electroconductive second film 33 between two insulating or semiconductive first films 32. In the electrode plate, the second film 33 is made electrically conductive with a high voltage power supply 3 by providing a surface exposure part 36 of the second film 33 and bringing it into contact with an electrical conducting plate 37 or by inserting an electrical conducting bar 42 to bring it into contact with the second film 33 perpendicularly or in parallel to a surface direction of the three-layer film 31.
