A bumper reinforcement formed by bending a sheet of a belt-shaped metal plate along a longitudinal direction of the metal plate and mounted to a vehicle body includes a first tubular portion and a second tubular portion both formed in a tubular shape by bending the metal plate along the longitudinal direction of the metal plate and a connecting portion formed by bending a middle portion in a width direction of the metal plate along the longitudinal direction of the metal plate. The middle portion is positioned between portions where the first tubular portion and the second tubular portion are formed. The connecting portion connects the first and second tubular portions and includes a first folding portion sandwiching a first end portion in the width direction of the metal plate and a second folding portion sandwiching a second end portion in the width direction of the metal plate. |
