Abstract
A liquid level detector is provided. A resistance plate has a plurality of conductive segments. A float vertically moves according to change of a liquid level to be measured. A float arm has one end attached to the float and the other end rotatably supported to rotate according to the vertical movement of the float. Contact points slide on the conductive segments with the rotation of the float arm according to the liquid level. The conductive segments are formed of a glass-sintered metallic body made of glass and gold alloy material containing a gold (Au) content equal to or greater than 18% by mass and less than 40% by mass. The contact points are formed of a gold alloy material containing a gold (Au) content equal to or greater than 32.5% by mass and less than 77% by mass.
