Abstract
A method for producing a press-formed product that includes a pair of flat sections and a bend section that connects the flat sections, in which a bending radius of the bend section is Rand an interior angle formed by the pair of flat sections is θ, includes the steps bellow. In the first forming step, an intermediate formed product including a bend section in which a bending radius is Rand an interior angle is θis formed. In the second forming step, a portion of a bend section of the intermediate formed product is formed into the bend section of the press-formed product. R, θ, Rand θsatisfy the conditions of Formulae (1) to (3) below:1.05<  (1);1.0<  (2);<6.0/()  (3),
