PROBLEM TO BE SOLVED: To provide a liquid level gauge that does not need to be closed using a diaphragm when filling a gel, and in which bubbles are less likely to be left inside a cavity.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. Inside the nozzle is provided a hole part whose diameter tapers off increasingly toward the tip of the nozzle part, the inside space and the hole part communicating with each other and being filled with a gel, the taper of the hole part differing with the contact angle of a material constituting the hole part.SELECTED DRAWING: Figure 2 |
