PROBLEM TO BE SOLVED: To provide a liquid level sensor capable of measuring precisely a liquid level. SOLUTION: This liquid level sensor has three sensor parts 2, 3, 4, and a measuring circuit 6, and the sensor parts 2, 3 are arranged on the first face 1a of a container 1 with a prescribed distance. The sensor part 4 is arranged on the second face 1b of the container 1, and is separated with prescribed distances respectively from the sensor parts 2, 3. An inclination angle of the container 1 is calculated on the basis of information from the liquid levels measured by the respective sensor parts 2, 3, 4. COPYRIGHT: (C)2005,JPO&NCIPI
