The invention discloses a manufacturing method of a gas spark switch electrode holder, which comprises the following steps of: (1) selecting a material for an electrode holder sleeve and processing data to ensure that the data meets set requirements; (2) adopting the selected material and the processed data in the step (1) to process a bowl-shaped electrode holder sleeve, mounting the electrode holder sleeve on the electrode holder, and forming a tenon-and-mortise structure between the electrode holder sleeve and the electrode holder to ensure that an internal horizontal contact surface of the electrode holder closely contacts an internal horizontal contact surface of the electrode holder sleeve; and (3) integrally pressing and connecting an electrode, the electrode holder sleeve and the electrode holder together. By using the gas spark switch electrode holder manufactured by the method provided by the invention, the electrode holder can be used repeatedly, and a gas switch can be updated by replacing an old electrode which has been used for a plurality of times, thereby multiplying the service life of the gas switch and reducing the running and maintenance cost of switch equipment.
