Summary:A columnar member able to absorb more energy at the time of collision without an accompanying increase in weight, that is, a columnar member 100 having at least a top plate 12 and two vertical walls 14, 16 connected to the top plate 12 at ridge parts 15 at both side edges 12a, 12b of the top plate and extending along the ridge parts 15, which columnar member having a bend inducing part 22 at least at part of the top plate 12 and having soft parts 14b, 16b at the two vertical walls 14, 16 at positions adjoining the ridge parts 15 and corresponding to the bend inducing part 22 in a direction of extension of the columnar member 100, the bend inducing part 22 being a part with a strength lower than the parts adjoining the bend inducing part 22 at the top plate 12, the soft parts 14b, 16b being parts with yield strengths lower than the parts adjoining the soft parts 14b, 16b at the vertical walls 14, 16, maximum lengths of the soft parts 14b, 16b in the direction of extension of the columnar member 100 being 0.01 time to 0.15 time the heights of the vertical walls 14, 16.
