PROBLEM TO BE SOLVED: To provide an inexpensive bent member in which deformation caused by the treatment to enhance the strength after the bending is small, corrosion resistance after coating is excellent, and absorption of impact energy is high. SOLUTION: The bent member is obtained by bending a metal plate, and a build-up weld part which enhances both the thickness and the strength and increases absorption of impact energy is provided on a ridge and/or an area in a vicinity of the ridge of at least one bent portion formed by bending the bent member. The build-up weld part is continuously, intermittently or partially provided along the ridge forming direction. COPYRIGHT: (C)2005,JPO&NCIPI
