The purpose of the present invention is to provide a low-cost and easily replaced cleaning brush which can carry out cleaning of a printed wiring board without damaging the same and without meandering on a transport path. This cleaning brush (10) is configured from brushes (11) having multiple brush members (11b) attached to core wires (11a), and when the brushes (11) are wound around a metal core (12), the brushes (11) to the left and right of the center are in a state inclined in opposite directions to each other at an equal interval while the extension lines (15), as seen in a plan view, of the core wires (11a) cross each other. Therefore, this cleaning brush (10): (1) can carry out cleaning on a printed wiring board without damaging the printed wiring board; (2) enables cleaning and transportation of the printed wiring board to be performed without meandering; and (3) can allow simple replacement operation at a low cost. |
