A screen printing machine for forming a print of paste supplied to a mask plate having pattern holes, includes: a flexible filling squeegee which performs a squeegeeing operation in which the filling squeegee is moved relative to the mask plate in a printing direction; and a scraping squeegee which is held to maintain a given interval from the filling squeegee in the printing direction and to be movable together with the filling squeegee in the printing direction, and which scraps off the paste remaining on the mask plate after passage of the filling squeegee. In the squeegeeing operation, the filling squeegee is pushed up and bent by the paste to provide a clearance between a bottom end of the filling squeegee and the mask plate with the paste interposed therebetween so that the pattern holes are filled with paste with a prescribed filling pressure.
