A press-formed body having a number of linear recessed parts formed in portions where a bending deformation or a unbending deformation is given at the time of press-forming, for example, in the side wall parts (31) of a formed body, characterized in that, where an interval between the linear recessed parts is P mm, the depth thereof is D mm, and the plate thickness of the press-formed body is t mm, D/P >= 0.03 x t/1.2 and 0.02t
