A crowning method applied to a press brake including an upper table and a lower table as being vertically opposed to each other and including first slits opened in right and left directions on both right and left sides of the upper table or the lower table, is by deforming end sides of upper portions or lower portions of the first slits of the upper table or the lower table upward or downward to carry out a crowning regulation.
