Abstract
An improved micro electrode and in its production method is disclosed. The electrode includes a tapering capillary tube of which the thicker end is 2 mm or smaller in the outside diameter, a conductive filament of 50 .mu.m or smaller in the outside diameter, an outer lead wire and a filler which is packed in the cavity of the capillary tube. The improvement comprising a direct connection of the conductive filament with the outer lead wire in the cavity of the capillary tube and the use of an insulating resin as the filler. The production method comprises a step of threading the conductive filament into the tapering capillary tube to make the tip of the filament project from the needle end of the capillary tube. The method is improved by filling at least part of the cavity of the capillary tube with a volatile solvent to facilitate the threading.
