Disclosed is an example of a method of manufacturing a pressed product including a substantially U-shaped main body and an undercut flange situated in the main body, in which an angle modification process can be eliminated. In the disclosed method, a third bent part, which is situated away from a first bent part towards a second bent part on a metallic sheet by a first length or more, is bent such that the first bent part is moved towards a first press direction and the undercut flange is moved towards a second press direction. The first press direction and the second press direction are opposite to each other. The first length is a length from a boundary between the undercut flange and a first plate portion to a tip of the undercut flange sized by projecting the undercut flange on an imaginary surface orthogonal to the first plate portion.
