Ultra-micro electrode for electrochemical analysis and method of manufacturing the same

A method of manufacturing an ultra-micro electrode to perform electrochemical analysis, the method comprising:

• preparing an insulating member which has a capillary shape with a hollow region formed along a longitudinal direction thereof;
• preparing a conductive wire formed of a conductive material which has an oxidation resistance that is greater than an oxidation resistance of copper;
• inserting the conductive wire into the hollow region of the insulating member;
• manufacturing half-finished products by applying heat and an external force to the insulating member which has the conductive wire inserted therein to stretch the insulating member and the conductive wire so that a central portion of the insulating member is made thin and the insulating member and the conductive wire are ruptured at central portions thereof;
• forming a groove that has a predetermined depth by etching the conductive wire located on a ruptured surface of each half-finished product;
• and
• forming a filling layer by filling the groove with a conductive material by a plating process.
