PROBLEM TO BE SOLVED: To provide an apparatus for cleaning a screen printing mask, by which wiping of a paste is efficiently performed for a screen printing mask corresponding to a cavity substrate, and to provide a screen printing machine and a method of cleaning a screen printing mask. SOLUTION: In the cleaning apparatus, a sliding contact region 34a of a paper member 34 is brought in sliding contact with the lower face of a mask region MRF corresponding to a flat part, wiping off a paste PT that is stuck to the lower face of the mask region MRF corresponding to the flat part. On the lower face of each projected part 3a in a mask region MRC corresponding to a cavity part, the sliding contact region 34a of the paper member 34 is successively brought in sliding contact, wiping off the paste PT that is stuck to the lower face of each projected part 3a. In wiping off the paste PT stuck to the lower face of each projected part 3a, the paper member 34 is wound during the time after the sliding contact region 34a of the paper member 3 is receded from one projected part 3a until coming into contact with other projected part 3a, thereby renewing the sliding contact region 34a of the paper member 34.
