<p>An internal resistor of a cathode-ray tube comprises an insulating substrate (21); a resistor layer (23) formed on one surface of the insulating substrate (21); a plurality of terminal electrodes (22A-22E) provided on the resistor layer (23); and a plurality of terminals (31A-31E) connected with the terminal electrodes (22A-22E). The terminals (31A-31E) each include a base of a nonmagnetic alloy and a surface layer consisting of an oxide of the same nonmagnetic alloy formed on the surface of the base, and they have a relative permeability less than 1.005. The surface layer of each terminal (31A-31E) is covered partially with an insulating layer. The nonmagnetic alloy is an alloy with a Ni-Cr base, and the surface layer is formed by oxidizing the surface of the terminal under the condition that NiO is unlikely to form.</p> |
