Abstract
A safety panel that is bonded to a front surface of a panel of a cathode ray tube envelope can be peeled easily without damaging the safety panel. A cathode ray tube (5) has a safety panel (3) that is bonded to a front surface of a panel (2) through a resin layer (4). When the safety panel (3) is to be peeled, the surface of the safety panel (3) is rapidly heated by a sheet-shaped infrared heater (6) and the resin layer (4) is heated up to a melting point and softened by the heat conduction. Then, a spatula (7) is inserted into a spacing between the safety pane (3) and the resin layer (4) to thereby peel the safety panel (3).
