<p>Provided is a screen printing device and a screen printing method capable of performing, in a screen printing with respect to an upper surface of a substrate and a bottom surface of a recess portion that is opened in the upper surface, efficient printing operations while ensuring preferable printing quality. In the screen printing, pastes are printed sequentially in two stages with respect to a cavity substrate having an upper surface printing area and a bottom surface printing area on the bottom surface of the recess portion by an upstream printing unit and a downstream printing unit including hermetically sealed squeegee mechanisms (36(1), 36(2)) provided with a first sliding contact plate (54A) and a second sliding contact plate (54B), respectively. In the screen printing, in the case where the bottom surface printing area is to be printed, residual pastes in an reentrant portion on an upper surface side of a fitting portion are scooped with the sliding contact plate disposed in a rearward position in a squeegeeing direction, thereby removing the residual pastes from the reentrant portion. In the case where the upper surface printing area is to be printed, the pastes adhered to an upper surface of an upper surface printing mask are scraped out with the sliding contact plate disposed in the rearward position in the squeegeeing direction.</p> |
