PROBLEM TO BE SOLVED: To provide a screen printer with improved printing accuracy configured so that paste rolling on a mask has a uniform rolling diameter in the longitudinal direction of a squeegee.SOLUTION: In screen printing, after a substrate 2 is brought into contact with a mask 14, a squeegee 16b is made to abut on the mask 14 and is moved horizontally. When the squeegee 16b is slid on the mask 14 to scrape paste Ps on the mask 14, an opening 14h formed on the mask 14 is filled with the paste Ps so as to transfer the paste Ps to the substrate 2. Relatively larger amount of paste Ps is supplied to a region where the paste Ps is scraped by an end of the squeegee 16b, compared to a region where the paste Ps is scraped by a central portion of the squeegee 16b on the mask 14. |
