Claims

[Scope of utility model registration request]

(1) In a microelectrode in which an extremely thin insertion tip that can be inserted into a cell is formed at the tip of a glass tube and the inside is filled with a drug solution, a portion of the tip of the insertion tip remains on the surface. A microelectrode characterized by forming a conductive film.

(2) The microelectrode according to claim 1, which is a registered utility model, in which a conductive film is formed on the glass tube in advance, and then heated, melted, and stretched to form an extremely thin insertion tip.

(3) The microelectrode according to claim 1, which is a registered utility model, in which the glass tube is heated and melted and stretched to form an extremely thin insertion tip, and then a conductive film is formed thereon.

(4) Utility model registration claim Paragraph 1, in which a plurality of glass tubes are bundled and the ultra-fine insertion tip is formed in close contact with one point;
The microelectrode according to item 2 or 3.

(5) The microelectrode according to claim 1, 2, 3, or 4, wherein the conductive film is formed by silver vapor deposition.
