1. A screen printing apparatus comprising: a mask stretched in a frame body fixed at a predetermined height position and having at least one pattern hole formed therein; a substrate holder that clamps and holds a substrate at sides of the substrate by a pair of clamping members below the mask; a substrate positioning part that upwardly and downwardly moves the substrate clamped by the clamping members to thereby bring the substrate into contact with the mask from an underside of the mask and position the substrate in a predetermined height position; a mask suction part that is provided in each of the clamping members and sucks the mask in contact with the substrate; a screen printing part that prints paste on the substrate through the at least one pattern hole formed in the mask by sliding a squeegee on the mask to which the paste is supplied; and a control unit for controlling the substrate positioning part and each mask suction part such that the mask is pressed up by a predetermined amount through contact with the substrate when the substrate is upwardly moved by the substrate positioning part and the mask is sucked by each mask suction part provided in each clamp member.
