A guard beam (1) of an automotive door structure can provide the guard beam which is relatively light in weight but have sufficient impact load absorbing capacity with stable strength at low cost. The guard beam (1) has a beam portion (3) and palm portions (2) at both ends of the beam portion integrally made of a high tension steel blank member. The beam portion has a substantially triangular cross section with a bottom plate portion (5), support plate portions (4) extending from a peak of the triangular configuration remote from the bottom plate portion (5) in a direction substantially perpendicular to the bottom plate portion (5) and side plate portions (6) each connecting each end of the support plate portions at the peak to the transverse edge of the bottom plate portion (5). <IMAGE>
