Abstract: An ultrasonic cleaning apparatus capable of cleaning large-sized objects includes: a casing having a bottom surface that forms a tilted surface to oppose the object to be cleaned and having an ultrasonic transducer provided at an inner lower surface; a cleaning liquid supply device configured to supply cleaning liquid to a casing bottom surface; and a flow-speed accelerator that ejects the cleaning liquid by accelerating the flow speed of the cleaning liquid from the cleaning liquid supply device. The casing is formed by a main body including an upper plate, a projected part attached to a lower part of the upper plate, an outer lateral face extended from the projected part in a downward direction, and the bottom surface connected integrally at a lower end part of the outer lateral face. The bottom surface is formed to be tilted at a prescribed angle with respect to a horizontal plane.
