PROBLEM TO BE SOLVED: To reliably prevent the occurrence of a surface crack during bending work.SOLUTION: In a method for bending a building-up material having building-up layers (2 and 3) formed on a surface of a base material 13, the base material 13 is bent to a target angle after the formation of the first building-up layer 2 on a surface of a half part, which is positioned on a bending-direction side, of the base material 13, and the second building-up layer 3 is formed on a surface of a half part, which is positioned on the side opposite to a bending direction, of the base material 13, in this state. |
