A cleaning apparatus in accordance with the present invention includes a first inflow section, provided on a first side surface of a cleaning tank having a substantially rectangular parallelopiped shape, having two inflow openings, a second inflow section, provided on a second side surface facing the first side surface, having inflow openings, and outflow openings for releasing a cleaning liquid flown in from the first and second inflow sections. The cleaning liquid flowing in from the inflow openings forms complex and strong flows in the cleaning tank, thus removing contaminants on a cleaning target evenly and efficiently without nonuniformity and preventing stagnation of the cleaning liquid in the cleaning tank. The cleaning liquid released in filtered by a circulatory section and is allowed to flow into the cleaning tank again through a pipe. As a result, it is possible to clean evenly and efficiently a large cleaning target such as a glass substrate used for liquid crystal display devices and other devices.

[ What is claimed is:] [1.]1. A cleaning apparatus, comprising:a cleaning tank having a substantially rectangular parallelopiped shape with a region for storing a cleaning target with an incline;a first inflow section for allowing a fluid to flow into said cleaning tank, said first inflow section provided on a position in a region on a first side surface of said cleaning tank in a vicinity of an upper end of the cleaning target inclined, the region corresponding to a distance between the upper end and a lower end of the cleaning target with respect to a bottom surface of said cleaning tank;a second inflow section for allowing the fluid to flow into said cleaning tank, said second inflow section provided on a second side surface facing the first side surface on which said first inflow section is provided so that a height of said second inflow section from the bottom surface of said cleaning tank is in a vicinity of the lower end of the cleaning target inclined; anda plurality of outflow openings for releasing the fluid flowing in from said first inflow section and said second inflow section, said plurality of outflow openings provided on the first side surface and the second side surface so as to contact an upper surface of said cleaning tank,wherein at least one of said first inflow section and said second inflow section has a plurality of inflow openings whose heights from the bottom surface of said cleaning tank are different from one another.
