A tubular type torsion beam is manufactured by bending and welding and coupling a plate material. The plate material has a plurality of protrusions disposed on a plurality of side surfaces in a width direction of the vehicle. The torsion beam is manufactured by molding the plate material in a pipe shape by bending the plate material in the width direction and molding the plate material to dispose the plurality of protrusions to contact each other to form a gap between the plurality of side surfaces of the plate material and then welding and coupling the plurality of side surfaces of the plate material.
