A method for manufacturing a vehicle body member in which a second sheet material is placed on and joined to a first sheet material and a joined sheet material formed by the joining of the first and second sheet members is press formed into a vehicle body member with a predetermined shape includes: a joining step of joining the second sheet material to the first sheet material by welding at a plurality of points including a first joint and a second joint which are separated from each other, thereby forming the joined sheet material; a forming step of press forming the joined sheet material so that a ridge crossing an imaginary line segment connecting the first joint and the second joint is formed in a portion where the first sheet material overlaps the second sheet material; and a preparation step of, before the joining step, forming a displacement facilitating portion, which facilitates displacement of the second sheet material relative to the first sheet material in a longitudinal direction of the imaginary line segment, in a portion corresponding to between the first joint and the second joint in the second sheet material.
