PROBLEM TO BE SOLVED: To provide a panel for a flat cathode ray tube capable of minimizing breakage in a heat treatment process and of reducing a production cost. SOLUTION: This panel of a flat cathode ray tube has a substantially flat outside surface and has an inside surface having a certain curvature. When it is assumed that the curvature radius on the diagonal axis of the panel effective screen is Rd, the cross-sectional curve radius (Rd/(1.767×diagonal length of the effective screen)) on the diagonal axis of the panel effective screen is Rz, the tip thickness of the panel effective screen is Ts, the maximum thickness of a boundary part between a panel skirt and the effective screen is Tm, and the panel center thickness is CFT, this panel for a flat cathode ray tube is characterized by forming the panel so that the value of (Ts/Tm)×CFT×Rz satisfies a range of 28 to 36.
