Provided is a vehicle impact beam that has an open cross-sectional shape, that has a main body section that is integrally formed with a pair of terminal sections, and that has increased strength. This vehicle impact beam is provided with an elongate main body section and with a pair of terminal sections that are connected to both longitudinal-direction ends of the main body section. The main body section and the pair of terminal sections are integrally formed by deforming a metallic steel sheet. As seen from the longitudinal direction, the main body section has an open cross-sectional shape, has a main-body-side protrusion that protrudes in a prescribed direction, and has a pair of inner flange parts that are provided so as to extend toward each other from both side ends of the main-body-side protrusion. As seen from the longitudinal direction of the main body section, the terminal sections have an open cross-sectional shape, have a terminal-side protrusion that protrudes in the same direction as the protrusion direction of the main-body-side protrusion, and have a pair of outer flange parts that are provided so as to extend away from each other from both sides of the terminal-side protrusion. |
