Method for producing sheet metal member

The present invention makes it less likely that an end of a tubular part is buckled when the thickness of the end is increased. This method for producing a sheet metal member includes a preformed material forming step (S350), a one-end thickening step (S352), and a shape-fixing step (S354). The preformed material forming step (S350) is a step for forming a preformed material. The preformed material (10) is provided with a tubular part. The one-end thickening step (S352) is a step for pressing a one-end thickening mold against an annularly-shaped one end (26) of the tubular part. The shape-fixing step (S354) is a step for fixing the shape of the one end. At the one-end thickening step (S352), the one end (26) of the tubular part is thickened in a state where the movement of the one end of the tubular part is restricted. 降低使筒状部的端部的壁厚增加时该端部弯曲的可能性。板金制部件的制造方法包括坯料形成工序(S350)、端增厚工序(S352)以及整形工序(S354)。坯料形成工序(S350)是形成坯料的工序。该坯料(10)具有筒状部(20)。端增厚工序(S352)是将端增厚用模具向筒状部的作为环状的端(26)按压的工序。整形工序(S354)是对该端进行整形的工序。在端增厚工序(S352)中，在限制筒状
