A flat cathode ray tube is provided. The flat cathode ray tube includes a shadow mask having a plurality of electron beam holes, a shadow mask frame having multiple-layered support members continuously connected, for supporting the shadow mask, and an inner shield connected to the shadow mask frame. The support member for supporting a shadow mask is solidified by forming multiple-layer laminates. Also, mobility is provided to the longer sides of the shadow mask, thereby easily applying a tension to the shadow mask.
