PROBLEM TO BE SOLVED: To provide a dust collector maintaining the dust collecting performance of a dust collecting part over a long period of time. SOLUTION: A plurality of electrode parts (71, 81) of a first electrode (41) comprises a first electrode part (81) and a first projection electrode part (71) whose projection length to the upstream side of air flow is formed larger than the first electrode part (81). A plurality of electrode parts (72, 82) of a second electrode (51) comprises a second electrode part (82) and a second projection electrode part (72) whose projection length to the upstream side of the air flow is formed larger than the second electrode part (82). The respective electrode parts (71, 72, 81, 82) of the first electrode (41) and the second electrode (51) are arrayed such that the upstream parts of the first projection electrode part (71) and the second projection electrode part (72) face each other and at least one set of the first electrode part (81) and the second electrode part (82) is provided between the downstream parts of the projection electrode parts (71, 72) of both electrodes.
