PROBLEM TO BE SOLVED: To provide a screen printing system 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 system. SOLUTION: This screen printing system includes: a first cleaning device 16a which removes paste Pst sticking to the lower surface of a projecting part 13t by successively bringing a mask contact region R, formed by putting a paper member 42 across the upper end of a nozzle part 41, into contact with the lower surface of each projecting part 13t of a first mask 13a; a second cleaning device 16b which removes the paste Pst sticking to the lower surface of a second mask 13b by bringing the mask contact region R formed by putting the paper member 42 across the upper end of the nozzle part 41, into contact with lower surface of the second mask 13b. The first cleaning device 16a takes up the paper member 42, while the paste Pst sticking to the lower surface of the projecting part 13t of the first mask 13a is removed. COPYRIGHT: (C)2011,JPO&INPIT
