摘要：
A liquid level detecting apparatus is provided. A resistance plate has a plurality of elongated conductive segments arranged therein. A float is configured to be moved upward and downward depending on a displacement of a liquid level to be measured. A floating arm has one end attached to the float and the other end rotatably supported to be rotated in response to upward and downward movements of the float. A contact is configured to be slid on the plurality of conductive segments in association with a rotation of the float arm depending on the liquid level. The plurality of conductive segments comprise a plurality of first segments made of a first metal material containing at least silver (Ag) and palladium (Pd), and a plurality of second segments made of a second metal material essentially containing gold (Au).
