A chassis structure for a plasma display module, and a plasma display module including the chassis structure effectively dissipate heat generated by a plasma display panel and improve assembly of the plasma display module. The chassis base includes: a front plate; a back plate separated from the front plate; and a heat dissipation member disposed between the front plate and the back plate, and having a bent cross-section arranged so that some surfaces of the heat dissipation member contact the front plate and some surfaces of the heat dissipation member contact the back plate to allow air flow between the front and back plate.
