Built-in resistor for cathode-ray tube

A cathode-ray tube comprising;

• an envelope constituted by a panel portion having a fluorescent screen formed on an inner surface thereof and by a funnel portion having a neck portion;
• and
• an electron gun disposed inside the neck portion and comprising a cathode body, a plurality of grid electrodes, and a resistor for loading a divided partial voltage to some of said plurality of grid electrodes;
• which is featured in that;
• said resistor comprises an insulating substrate, a resistance layer formed on one main surface of the insulating substrate, a plurality of terminal electrodes mounted on the resistance layer, and a plurality of terminals connected respectively with said terminal electrodes;
• wherein said plurality of terminals are individually constituted by a base body comprising a non-magnetic alloy, and by a surface layer which is formed on the surface of the base body and comprising an oxide of said non-magnetic alloy;
• said plurality of terminals have a relative permeability of not more than 1.005;
• and said surface layer of each of the terminals is partially provided with an insulating covering layer.
