<p>PROBLEM TO BE SOLVED: To provide an angle detector that has high rotational position detection accuracy by suppressing relative position variations of yokes between respective phases.SOLUTION: Provided is an angle detector that detects the rotation angle of a rotator plate 6 by allowing the rotation of the rotator plate 6 to change a magnetic flux passing through a magnetic flux circuit plate. The angle detector comprises: a wiring core 3 around which a coil is wound and that forms a magnetic flux on the rotational orbit of the rotator plate 6 rotating about a rotating shaft; a lower part magnetic flux circuit plate 5 laminated in a rotating shaft direction of the wiring core 3; and an upper part magnetic flux circuit plate 4 that is laminated on a side opposite to a side on which the lower part magnetic flux circuit plate 5 is laminated in the rotating shaft direction of the wiring core 3, thereby forming a gap with the lower part magnetic flux circuit plate 5. The wiring core 3 has an insulating part for insulating the coil from the outside. The insulating part has a fixing part for relatively fixing the upper part magnetic flux circuit plate 4 and the lower part magnetic flux circuit plate 5.</p> |
