In a CRT inner resistor (1), it is intended to prevent the potential of an electrode (12) from being varied owing to leak current that is caused by electric field concentration on the circumferential portion of the electrode because an insulating substrate (11) is charged with stray electrons. An insulating substrate, and electrodes and a resistive body (13) that are connected to each other are provided. An insulating glass layer (14) is provided on the insulating substrate so as to cover the resistive body. Shield members (15) made of insulating glass are provided along the circumferences of the respective electrodes so as to cover the peripheries of the respective electrodes and the portions outside the peripheries of the respective electrodes. The shield members prevent charging of the portions of the insulating substrate outside the peripheries of the respective electrodes and in their vicinities, prevent electric field concentration in the vicinity of the peripheries of the respective electrodes, and inhibit the occurrence of leak current. <IMAGE> |
