Abstract
A pressed article manufacturing method employing a press mold equipped with a punch and a die to manufacture a pressed article including a first wall, a second wall extending out from an end portion on at least one length direction side of the first wall toward a back face side of the first wall, and a third wall extending out from a leading end portion of the second wall toward a front face side of the second wall. The manufacturing method includes using the punch and the die to apply pressure to and grip a portion on a base end side of the second wall in a first warp shape in which the base end side portion is warped so as to be convex on a back face side of the second wall as viewed in lateral cross-section in a state prior to demolding from the press mold.
