A door impact beam includes a top plate, a recessed bead, and walls. The top plate faces an outer panel that constitutes a door of the vehicle and extends in the front-rear direction of the vehicle. The recessed bead is disposed on the top plate and has a U shape toward an inner panel that constitutes the door of the vehicle. The walls protrude toward the inner panel from both ends of the top plate in a width direction of the top plate. The door impact beam is formed by press-molding a sheet-metal composite. The sheet-metal composite includes a sheet-metal main body and a reinforcing sheet metal overlapping with a part of the sheet-metal main body in a longitudinal direction. The door impact beam extends in a front-rear direction of the vehicle in an internal space formed by the outer panel and the inner panel.
