An impact absorber absorbs impact energy when receiving an impact load. The impact absorber includes a fibrous structure and a matrix resin. The fibrous structure includes a tube of which a center axis extends in a direction in which the impact load is applied and a rib that connects opposing inner surfaces of the tube to each other. The fibrous structure is impregnated with the matrix resin. The direction in which the impact load is applied is referred to as an X direction, and a direction in which the rib connects the opposing inner surfaces of the tube to each other is referred to as a Y direction. The tube includes a fiber layer including load direction yarns, which are formed from reinforcement fibers, extending in the X direction and intersecting direction yarns, which are formed from reinforcement fibers, intersecting the load direction yarns. The rib includes yarns, which are formed from reinforcement fibers, extending only in a direction orthogonal to the X direction.
