Abstract
A liquid surface detecting device includes a movable body, a circuit board, segment electrodes, an output electrode, and a resistive element located across the segment electrodes and the output electrode to be electrically connected thereto. The segment electrodes are arranged on the mounting surface in an electrode region. The resistive element includes first and second resistive portions on both sides of the electrode region in the movement direction. The resistive element is electrically connected to the output electrode at each of the first and second resistive portions. The movement direction in which the movable body moves according to a decrease of the liquid surface level is defined as a reference direction. The second resistive portion located further in the reference direction than the first resistive portion is completely cut off to block a conduction between its output electrode side and electrode region side.
