Screen printing apparatus

A screen printing apparatus in which a squeegee is slid on a mask contacting a board to print paste onto the board via pattern holes formed in the mask, said screen printing apparatus comprising:

• a box-like member comprising a top-plate portion in which first suction hole and a second section hole are formed and which is allowed to contact a lower surface of the board;
• a blower suction pipe which communicates with an internal space of the box-like member, and which extends outside the box-like member;
• a blower suction source which sucks air through the blower suction pipe to generate a blower suction force in the first suction hole;
• a vacuum suction pipe which is connected to the second suction hole, and which extends through the internal space of the box-like member to an outside of the box-like member;
• and
• a vacuum pressure supplying device which supplies a vacuum pressure to the second suction hole through the vacuum suction pipe.
