PROBLEM TO BE SOLVED: To provide a screen printing machine performing sufficient cleaning of a mask to be used for screen printing of a cavity substrate, and a method for cleaning the mask of the screen printing machine. SOLUTION: This screen printing machine is equipped with a cleaning device 16 which removes paste Pst sticking to the lower surface of a projecting part 13t in relatively moving to a mask 13. In this case, a mask contact region R formed by putting a paper member 42 across the upper end of a nozzle part 41, is successively brought into contact with the lower surface of each projecting part 13t of a mask region MRC corresponding with a cavity member. In addition, the cleaning device 16 includes a paper member take-up mechanism 57 which takes up the paper member 42, while the paste Pst sticking to the lower surface of the projecting part 13t of the mask region MRC corresponding with the cavity part, is removed.
