This invention discloses a composite probe of microinjection and micro ring electrode and method of manufacture, whose characteristic is: Firstly draw one end of glass capillary to cone by heat-drawing process; aggradate electrode film on the outside gauge from conical tip to the back end; set a parallel conductor at the axes direction of glass capillary, and the electrode film is bonded to the conductor at the conical back end by conducting resin; pull the bonded electrode film and conductor into insulating tube, whose both ends are sealed by epoxide resinl, then aggradate insulating film outside the electrode film at conical front end, lastly incise the insulating film aggradating conical tip out from the electrode film surface. |
