Abstract
A method of production of a shaped article able to suppress occurrence of shaping defects, that is, a method of production of a shaped article including a first step of press-forming a metal plate () into a U-shape to obtain a U-shaped article () having a bottom part () straight extending in a longitudinal direction and a second step of press-forming the U-shaped article () to bend it in the longitudinal direction so that the bottom part () of the part projects to the inside and obtain a U-cross-section bent article ().
