Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid level gauge with which it is possible to prevent the breakage of a diaphragm and increase resistance to chemicals and moisture permeation while suppressing costs.SOLUTION: The liquid level gauge has a body part provided with a pressure sensor in an inside space and a nozzle part extending from the body part and having a passage formed therein. The inside space and the passage communicate with each other, and a first gel is filled in the passage on the tip side of the nozzle part and a second gel is filled in the passage on the rear end side of the nozzle part and the inside space, the second gel having its boundary with the first gel covered with a metal thin-film.SELECTED DRAWING: Figure 1 【課題】ダイアフラムの破損を防止でき、かつ、コストを抑えつつ耐薬品性や耐透湿性を高めることのできる液面計を提供する。【解決手段】内部空間に圧力センサを備えた本体部と、本体部から延び、内部に流路が形成されたノズル部とを有し、内部空間と流路は互いに連通され、ノズル部の先端側の流路に第１ゲルが充填され、ノズル部の後端側の流路及び内部空間に第２ゲルが充填され、第２ゲルは、第１ゲルとの境界面が金属薄膜で覆われている。【選択図】図１
