MAGNETIC SENSOR DEVICE
First Claim
1. A magnetic sensor device comprising:
- a magnet;
a magnetic-resistance-effect-element mounted substrate including a magnetic-resistance-effect-element mounted body mounted on a surface thereof opposite to a surface thereof facing the magnet, the magnetic-resistance-effect-element mounted body formed along a longitudinal direction of the magnet;
a case that accommodates or retains the magnet and the magnetic-resistance-effect-element mounted substrate; and
a magnetic shield to cover the case except for the surface of the magnetic-resistance-effect-element mounted substrate on which the magnetic-resistance-effect-element mounted body is mounted, whereinthe magnetic shield comprises;
a bottom that faces a surface of the case, the surface being disposed so as to oppose the magnetic-resistance-effect-element mounted substrate across the magnet, andside walls standing from the bottom toward a side adjacent to the magnetic-resistance-effect-element mounted substrate, the side walls being spaced from each other in a transverse direction intersecting the longitudinal direction, the side walls extending in the longitudinal direction of the magnet, andthe side walls have ends on the side adjacent to the magnetic-resistance-effect-element mounted substrate, the ends being located between a position of a surface where the magnetic-resistance-effect-element mounted substrate opposes the magnet and a position of a surface where the magnetic-resistance-effect-element mounted body is mounted on the magnetic-resistance-effect-element mounted substrate.

Abstract
A magnetic sensor device includes: a magnet; a magnetic-resistance-effect-element mounted substrate on which a magnetic-resistance-effect-element mounted body is mounted on a surface thereof opposite to a surface thereof facing the magnet, the magnetic-resistance-effect-element mounted body extending in the longitudinal direction of the magnet; a case that accommodates or retains the magnet and the magnetic-resistance-effect-element mounted substrate; and a magnetic shield that covers the case except for the surface of the magnetic-resistance-effect-element mounted substrate on which is mounted the magnetic-resistance-effect-element mounted body. The magnetic shield covers the case at a position corresponding to the surface of the magnetic-resistance-effect-element mounted substrate facing the magnet, or from the position corresponding to the surface of the magnetic-resistance-effect-element mounted substrate facing the magnet to a side of the case opposite to the magnet.
