Since a continuous fiber of a fiber-reinforced resin member includes an axial fiber aligned in the axial direction and an axially right-angled fiber aligned at right angles to the axial direction, and the density of the axially right-angled fiber of a first layer on the outer side of the corner part is made higher than the density of the axially right-angled fiber of a second layer on the inner side of the corner part, when an axial load is input and the fiber-reinforced resin member breaks, the axially right-angled fiber disposed at high density in the outside first layer of the corner part is actively stretched and breaks, thereby enabling a large energy-absorbing effect to be exhibited. Moreover, the fiber-reinforced resin member has a simple structure in which merely the density of the axially right-angled fiber in its interior is changed, thereby minimizing any increase in the production cost.
