PROBLEM TO BE SOLVED: To provide a screen printing machine which can form a paste layer in a thick film on a printed object in shorter printing time. SOLUTION: The screen printing machine is the type which forms patterns with paste on the printed object (110) and has; a printing screen (201) on which a micropore pattern is formed and which is arranged with predetermined space against the printed object, paste (51) supplied onto the printing screen, a main squeegee (111a) which moves forward on the printing screen and closely contacts the printing screen and the printed object and extrudes the paste on the surface of the printed object through the micropore, an auxiliary squeegee (111b) which moves on the surface of the printing screen following and keeping the predetermined distance with the main squeegee and forms an osculating plane with the surface of the printed object and the printing screen behind the main squeegee. The main squeegee and the auxiliary squeegee moves simultaneously forward and the travelling speed of both squeegees is twice to three times faster than the marginal travelling speed of the squeegee compared with the speed of single squeegee screen printing.
