To provide a method and apparatus for manufacturing a printed board having no fear breaking a part of a printing pattern, easily forming printing paste into a thick film and capable of obtaining printed wiring of high accuracy.

A large number of electromagnets 8 as a magnetic force generation mechanism are parallelly built in a mount base 7 of a thick film circuit printing apparatus under the board 6 to be printed. Herein, a printing squeegee 4 scans a screen mask 3 comprising a screen 1 and a photosensitive emulsion 2 to push out silver paste 5 on the upper surface of the board 6 to be printed. Thereafter, all of the electromagnets 8 are turned ON to make the magnetic fields of them effective. Subsequently, the screen mask 3 is separated by 2 mm from the board 6 to be printed to perform plate separation.
