The printing plate has a metal sheet () provided with a squeegee cleaning section () formed thereon and fixed to the back surface of a slanting area () of mask () attached to a plate framework (). The through hole of the printed circuit board is filled with paste only after paste of high viscosity adhering to the edge of the squeegee is removed by the squeegee cleaning section (), to prevent the paste from being left on the through hole, and thereby achieving the printed circuit board of excellent quality.
