摘要： A cathode ray tube has a contact spring 30 which is fixed at one end to a shield cup 27 provided on an anode electrode 26 of an electron gun assembly and is pressed at the other end against an electrically conductive coating 3a applied to an inner wall of a funnel portion 3, so as to provide a reliable electrical connection between the anode electrode 26 and the electric conductive coating 3a and to hold the electron gun assembly coaxially in the neck portion 2. The contact spring 30 is made of an alloy material which is composed of 30-35 wt % nickel (Ni), 19-23 wt % chromium (Cr) and the balance of which is substantially iron (Fe), and which has a micro Vickers hardness of 250-400.
