<P>PROBLEM TO BE SOLVED: To improve the dust collection efficiency of an electric dust collection filter by extending the flow distance of sucked air around a repulsive electrode and a dust collecting electrode. Ž<P>SOLUTION: The dust collecting electrode 7a and the dust collecting electrode 7b are consisting of a sheet metal or an electroconductive resin of a sheet shape and two or more louvered parts 8 are formed at its surface. Air flow passage is made to meander thereby and a path where air passes in a dust collection part 6 can be made longer than a case of straight air flow passage. Consequently dust charged at a charging part 5 can be easily collected by coming into contact with the dust collecting electrode 7a and the dust collecting electrode 7b to improve the dust collection efficiency.
