摘要：
A method for bending a flat workpiece is provided. The method may include applying heat or pressure to the workpiece at a range within a first width from an edge with a residual stress formed by cutting so as to reduce the residual stress, and bending the workpiece along a bending line after applying the heat or pressure.
