PROBLEM TO BE SOLVED: To provide a screen printer and a component mounting line, which are enabled to retain an excellent printing accuracy by making the removal of a printing plate smooth and which are advantageous in terms of cost.SOLUTION: In a screen printer 5, a substrate holding unit 21 holding a substrate 2 is brought into contact with the lower face of a mask 13 formed with a pattern hole 13P, and a paste Pst on the mask 13 is scraped by sliding a squeeze 52 on the mask 13 in contact with the substrate 2 thereby to charge the pattern hole 13P of the mask 13 with the paste Pst. After this, the mask 13 and the substrate holding unit 21 are spaced for a snap-off. The substrate holding unit 21 holds the substrate 2 by clamping, by a pair of clamp members 37, the side faces of the substrate 2 received from the lower side by a lower receiving part 35. The lower receiving part 35 is equipped with bias means 40 including a mask abutment part 43 for abutting against the mask 13 while the substrate 2 and the mask 13 are in contact with each other, and an elastic body 44 for biasing the mask abutment part 43 upward. |
