Abstract
In making electrode construction for multiple cathode type flat cathode ray tube, a plural number of parallel strip electrodes are connected to form one sheet by means of connecting means 21, 21 . . . provided between neighboring strips. The connecting means are ribs extending laterally (i.e., in a direction of right angle to said strips from the strip electrodes 33, 33 . . . or 36, 36 . . . . The composite parallel strips formed by connecting by the connecting means are formed by photolithographic process from an Ni-Cr-Fe sheet. The connecting means are cut out by impingement of high energy beams (of laser or electron) after bonding the composite parallel strips onto another higher rigidity electrode member.
