A door beam includes an outer flange, an inner flange, and a pair of webs connecting the outer flange and the inner flange. The outer flange, the inner flange, and the pair of webs define a closed cross-sectional portion. The outer flange includes an outer central portion constituting the closed cross-sectional portion, and outer protruding portions protruding outward from the closed cross-sectional portion. The inner flange is formed with an attachment press working portion having been subjected to press working so as to serve as an attachment portion with respect to the inner panel at both end portions in the longitudinal direction. The outer protruding portion is formed with a mastic press working portion having been subjected to press working so as to serve as an attachment portion with respect to the outer panel.
