PROBLEM TO BE SOLVED: To provide a dust collector for an air conditioner that allows a discharge device to be surely mounted at an appropriate position enabling electrification contact between a discharge device side terminal and a dust collector side terminal at the time of mounting the discharge device to the dust collector.SOLUTION: A dust collector comprises: a filter installed on the upstream side of an air intake port of an air conditioner to remove dust from intake air； and a discharge device mounted on the air intake port side of a mounting frame installed between the air intake port and the filter and storing an electrode inside a frame having openings on the windward side and the leeward side. The discharge device includes a discharge device side terminal exposed to the outer surface of the frame and connected to the electrode, the mounting frame includes a mounting frame side terminal installed at a position facing the discharge device side terminal of the discharge device mounted to the mounting frame, and an edge of the air intake port is provided with pressing means abutting on the frame of the discharge device mounted to the mounting frame to bring the discharge device side terminal and the mounting frame side terminal into contact with each other.SELECTED DRAWING: Figure 4
