Abstract: There is provided a press brake (1) that, if subjecting a workpiece (90) having non-uniform thickness to bending, can efficiently give uniform curvature to the workpiece (90). The press brake (1) includes: a die (2) supporting the workpiece (90); a punch supporting member (4) arranged so as to be opposed to the die (2); a moving mechanism (5) that moves the punch supporting member (4) relative to the die (2); a punch (3) that is supported by the punch supporting member (4), is opposed to the die (2) or the workpiece (90) in a relative movement direction of the punch supporting member (4), and includes punch elements (3a) lined up in a direction orthogonal to the relative movement direction; and punch element adjusting mechanisms that are disposed so as to correspond to the respective punch elements (3a) and adjusts positions of the punch elements (3a) relative to the punch supporting member (4) in the relative movement direction.
