Minute electrode for electrochemical analysis
First Claim
1. A minute electrode for electrochemical analysis characterized in that it is comprised of a bundle of carbon fibers covered with a nonconducting resin, wherein ends of said carbon fibers are recessed from one end of the resin and wherein micro-holes extending to the outside in the direction of the longitudinal axis of the bundle of fibers are provided.

Abstract
A minute electrode comprised of a bundle of carbon fibers covered with a nonconducting resin, and the ends of the carbon fibers recesses at one end of the resin, and has the micro-holes released to the outside.
This electrode has small flow sensitivity and is not subject to be contaminated by interference substances.
The minute electrode of this invention is useful for various electrodes for the electrochemical analysis.
