Abstract: The present disclosure provides a magnetic sensor with improved accuracy or reliability. The magnetic sensor includes a first magnetism detection element that outputs a first detection signal, a second magnetism detection element that outputs a second detection signal, and a detection circuit that receives the first and second detection signals. The detection circuit corrects the first detection signal for each section in a ( 1/16n) period of the first detection signal, when n is a natural number. With this configuration, the magnetic sensor has high accuracy or high reliability, and therefore is useful as, for example, a magnetic sensor used for detecting a steering angle and the like of a vehicle.

Abstract: A rotation detecting device includes first and second magnetic detection elements that output first and second signals and a detection circuit having the first and second signals input thereto. The detection circuit includes an automatic correction circuit that performs generating and updating of a correction value for correcting the and second signals. The automatic correction circuit is configured to stop the generating or the updating of the correction value in at least one of a case where a rotation direction of an object is changed to a reverse rotation direction from a normal rotation direction and a case where a rotation direction of the object is changed to the normal rotation direction from the reverse rotation direction.

Abstract: A sensor includes a sensor element, a package accommodating the sensor element in an inside of the package, a grounding electrode disposed in the package, a lid covering an opening of the package, and a lead extending from the package. The lead includes first and second portions. The first portion of the lead is electrically connected to the grounding electrode and extends along a side surface of the package with a gap provided between the first portion and the side surface. The second portion of the lead is disposed between the lid and the package and extends toward the inside of the package. In this sensor, the opening can be sealed without soldering and reliably connect the lid to the grounding electrode.
