In a printed-wiring board produced by arranging a plurality of wiring circuit patterns on a printed-wiring board by screen printing and cutting out product regions corresponding to the wiring circuit patterns by punching them along the circumferences of the product regions, the printed-wiring board according to the present invention comprises deviation detecting patterns for determining whether or not the condition of deviation of the printed pattern is within an allowable limit, the deviation detecting patterns being printed at the time of the screen printing of the wiring circuit patterns in the vicinity of the position of the cut plane of the board for each product region of each wiring circuit pattern. Thereby, it is made possible to easily determine whether or not the condition of the pattern deviation is within a specified allowable limit.
