Abstract
A cleaning apparatus for cleaning an object to be cleaned by allowing a cleaning medium caused to fly by an air flow to collide with the object to be cleaned is provided. The cleaning apparatus includes a cleaning tank in which the cleaning medium is caused to fly by the air flow and which has an opening to allow the object to be cleaned to pass through; a cleaning medium accelerating part provided at a bottom part of the cleaning tank and to inject the air flow to cause the cleaning medium to fly; a hollow elongated member having substantially the same inner diameter as a diameter of the opening, connected outside the opening, and configured to form a movement path for the object to be cleaned; and a cleaning medium returning part to return the cleaning medium stagnant in the hollow elongated member into the cleaning tank.
