Abstract
A liquid level detecting device for detecting liquid level contained in a tank includes a float and an arm that moves in a prescribed manner when liquid level changes, a permanent magnet for forming a magnetic field, a hall IC for generating an electric signal in response to the motion of the magnetic field, a rotary member linked with the arm and the permanent magnet for moving the magnetic field relative to the hall IC as the float and the arm move, a terminal member for connecting the hall IC to an outside control circuit; and a mold body including a resinous holder for holding the hall IC and the terminal member. The resinous holder includes a sheath for insulating the hall IC from heat and mechanical stress generated when the mold body is formed.
