<P>PROBLEM TO BE SOLVED: To provide a rotation angle detecting device allowing a smaller diameter thereof despite the use of a magneto-electric IC in which a magnetic field detection unit is disposed substantially perpendicular to a signal computation unit, and a manufacturing method thereof allowing easy and efficient resin molding of the magneto-electric IC in which the magnetic field detection unit is set substantially perpendicular to the signal computation unit. <P>SOLUTION: A rotation angle detecting device comprises: a magnetic field detection unit 45 for detecting a change in magnetism perpendicular to a rotation axis ZS due to relative rotation with a rotation member having a field member; a signal computation unit 47 for outputting a rotation angle signal according to the change in the magnetism detected by the magnetic field detection unit 45; and leads 46 for connecting the magnetic field detection unit 45 and the signal computation unit 47. A bottom surface 47M of the signal computation unit 47 is disposed parallel to the rotation axis. A bottom surface 45M of the magnetic field detection unit is disposed perpendicular to the rotation axis. The rotation angle detecting device also comprises a magneto-electric conversion IC 44 bent in a substantially S-shape in which the leads are bent in a direction of deviating from the rotation axis and then bent in a reverse direction between the signal computation unit and the magnetic field detection unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
