    • A built-in resistor for cathode-ray tube which 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 the terminal electrodes, wherein the plurality of terminals are individually constituted by a base body made of a non-magnetic alloy, and by a surface layer which is formed on the surface of the base body and made of an oxide of the non-magnetic alloy, the plurality of terminals have a relative permeability of not more than 1.005, and the surface layer of each of the terminals is partially provided with an insulating covering layer. The nonmagnetic alloy is a Ni—Cr-based alloy, and the surface layer is formed through an oxidation treatment under a condition where the formation of NiO can be suppressed.
    • 一种用于阴极射线管的内置电阻器,其包括绝缘基板,形成在绝缘基板的一个主表面上的电阻层,安装在电阻层上的多个端子电极和分别与端子连接的多个端子 电极,其中所述多个端子由非磁性合金制的基体单独构成,并且由形成在基体的表面上并由非磁性合金的氧化物构成的表面层构成, 多个端子的相对磁导率不大于1.005,并且每个端子的表面层部分地设置有绝缘覆盖层。 非磁性合金是Ni-Cr系合金,在能够抑制NiO的形成的条件下,通过氧化处理形成表面层。
