Abstract: A method for fabricating an indirectly-heated cathode structure including inserting a heater into a mold, injecting a thermoplastic resin into the space of the mold to embed the heater in the thermoplastic resin, inserting the heater embedded in the thermoplastic resin into a sleeve having a cap on an end, connecting the sleeve and the heater using a support body to assemble a cathode structure, and heating the cathode structure to remove the thermoplastic resin from the cathode structure. Therefore, in an indirectly-heated cathode structure, deviation of a heater from a center position in a sleeve can be prevented, and it is easy to adjust the gap between a heater, a sleeve, and a cap. Thus, the heater can be positioned at a desired position inside the sleeve, preventing current leakage due to a breakdown in the heater. In particular, the sleeve and the cap can be uniformly heated, reducing a local difference in thermion emitting density.
