A process for manufacturing a dispenser cathode is disclosed, and the process comprises the steps of filling a porous base material into a storage tank, welding the storage tank to a cylindrical sleeve, installing a heater into the sleeve which has, a supporting face to be welded with the storage tank, an outside diameter which is larger than that of the storage tank, and an opening which is smaller than the outside diameter of the storage tank, wherein the heat transfer to the porous base material during the welding is prevented and the thermal efficiency is improved during the operation of the cathode so that a superior cathode characteristic is achieved.
