An energy absorber is crushed upon receiving compressive load, thereby absorbing energy. The energy absorber has a first end and a second end with respect to a direction of the compressive load. The energy absorber is formed of fiber-reinforced resin. The fiber-reinforced resin includes a stack of fiber layers having a compression direction fiber layer. The compression direction fiber layer includes fiber bundles of filament fibers. The fiber bundles are arranged such that the extending direction of the fiber bundles has a component of the direction of the compressive load. The density of the fiber bundles is gradually increased from the first end to the second end. Therefore, compressive load required for crushing is prevented from increasing at an early stage of crushing.
