ABSTRACT:
A liquid level sensor includes a housing, a rotary shaft which is rotatably provided in the housing, a magnet which is fixed to the rotary shaft, and rotating together with the rotary shaft, a pair of stators which are disposed so as to face an outer peripheral surface of the magnet, and an electronic circuit which includes at least a set of terminals and a magnetoelectric transducing element for detecting a change of magnetic flux in the stators caused by rotation of the magnet and for outputting an electric signal. The magnetoelectric transducing element and the stators are electrically connected and fixed to the set of terminals so that a terminal assembly is formed. The housing is formed by insert molding the terminal assembly with resin so that the terminal assembly is embedded in the housing.
