A door beam including an aluminum alloy extruded material of a closed section structure having a welded part along the longitudinal direction, webs and an outer flange are inhibited from buckling and further the welded part in the outer flange is inhibited from breaking at the time of collision. In a cross section of an aluminum alloy extruded material perpendicular to the extrusion direction, each of the webs includes an outer part connected to the outer flange and an inner part connected to an inner flange and the thickness of the outer part is larger than the thickness of the inner part. Each of the outer parts is positioned in a region outside a cross section center of the aluminum alloy extruded material in the vehicle body width direction.
