A heat-sink of a plasma display device is provided to improve productivity and to simplify a manufacturing process by forming a lateral air current path and a longitudinal air current path. A heat-sink(100) includes a plurality of heat-radiating parts(106) and a plate part(104). The heat-radiating parts are formed with protrusive shapes by performing an extrusion process using an extrusion die(410) and a rolling process using a molding roller. The plate part includes a lateral air current path(110) and a longitudinal air current path(112) which are formed by the protrusive heat-radiating parts. The plate parts include bent parts(102) which are protruded in an opposite direction of the protrusive direction of the heat-radiating part. The heat-sink has a symmetrical structure.
