The invention provides a cross beam for an automobile, an energy absorption box, a cross beam assembly, an energy absorption core plate and a manufacturing method of the energy absorption core plate. The cross beam for the automobile comprises a cross beam body; the energy absorption core plate is arranged in the cross beam body, the energy absorption core plate comprises a bent plate, the protruding side and the concave side of the bent plate are arranged in the front-back direction, and energy absorption holes distributed in the length direction of the bent plate section in an array mode are formed in the bent plate section of the bent plate. The double effects of collision resistance and light weight of the cross beam assembly can be achieved.
