Abstract
Provided is a fuel level sensing apparatus for a fuel tank for sensing a remaining fuel level of the fuel tank through a variation in a measured resistance value depending on a position of a wiper in contact with a resistance substrate. The resistance substrate includes a first segment part and a second segment part disposed to be spaced apart from each other. A resistance setting part of the second segment part is connected to positive electrode terminals, and a connecting part of the first segment part is connected to a negative electrode terminal by a negative electrode lead. A connection point of the negative electrode lead connected to the connecting part is formed between both ends of the connecting part in a length direction. A resistance deviation in a measured resistance value depending on a change in the position of the wiper may be reduced.
