PURPOSE: To provide a hole-plugging printing method for a printed wiring board capable of satisfactorily filling a blind hole with a filling agent with no air bubble inside the hole, and a plate for the method. MEANS: A window (11) of a metallic plate (10) is defined in a position shifted from a via hole (81) in a board (82) to the downstream side in the direction (F) of the movement of a squeegee (93). A recess (12) that is continuous with the window (11) is defined on the upstream side of the window (11). When the filling agent (90) is squeezed by the squeegee (93), the filling agent (90) first flows through the window (11) into a portion of the via hole (81) the downstream side in the direction of the movement of the squeegee (93), and spreads out toward the upstream side. As a consequence, air is not confined in the via hole (81), and the via hole (81) is filled satisfactorily with the filling agent (90).
