A small glass electrode and process for preparation thereof are disclosed. This small glass electrode is characterized in that said glass electrode, which has a bonded structure comprises a reference electrode composed of silver/silver chloride, a glass substrate having a pad embedded therein, said pad being composed of gold or platinum and circuit-connected to the reference electrode, and a silicon substrate having a (100) plane selectively etched by the anisotropic etching technique and comprising a groove for injecting an electrolyte composed of an aqueous solution containing chlorine such as KCl, or HCl, at least one hole for holding the electrolyte and a glass film formed in a portion corresponding to the reference electrode. By this structure, the small glass electrode can be easily manufactured at a low cost.
