Abstract:
1. An angle sensor device for detecting rotation angle of a rotatable member, comprising: a molded body constructed of resin; a pair of magnetic force detectors buried in the body and detecting alteration of magnetic force caused by rotation of the rotatable member and outputting signals depending on the rotation angle of the rotatable member; and a pair of mounting terminals each having a base portion; wherein each of the magnetic force detectors comprises: a sensing unit detecting the alteration of magnetic force and outputting first signals depending on the alteration of magnetic force; and a computing unit coupled with the sensing unit in L-shape and computing based on the first signals from the sensing unit and then outputting second signals depending on the rotation angle of the rotatable member, wherein the computing units are entirely buried in the body, wherein the magnetic force detectors are opposite each other, such that the sensing unit of one of the magnetic force detectors is positioned on the sensing unit of the other magnetic force detector, wherein the molded body defines a cavity surrounded by the magnetic force detectors; and wherein the base portions are exposed at an inner wall defining the cavity.
