A cathode structural body for cathode ray tube is characterized by bimetal cathode support (12). The bimetal for cathode support (12) consists of nickel-chromium alloy for the inner layer and nickel for the outer layer. The nickel-chromium alloy is blackened by steam moistening. The cathode structural body can minimize the variance of brightness of the CRT screen by minimizing the current change of cathode using the bimetal at an incipient stage.
