MAGNETIC SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18610999 titled 'MAGNETIC SENSOR
The magnetic sensor described in the patent application consists of a magnetic sensor chip with a magnetoresistive effect element and a sealed part. The magnetoresistive effect element includes a free layer and a pinned layer, while the sealed part has a first surface and a second surface, which is opposite the first surface. The shape of the sealed part in the plan view is substantially quadrilateral, with a first side and a second side that are parallel to each other. The magnetization direction of the pinned layer, when no external magnetic field is applied, is inclined with respect to a straight line found through the least squares method using points set on the first side.

Original Abstract Submitted
A magnetic sensor includes a magnetic sensor chip that includes a magnetoresistive effect element and a sealed part. The magnetoresistive effect element includes a free layer and a pinned layer. The sealed part has a first surface and a second surface, which is opposite the first surface. The shape of the sealed part in the plan view from the first surface side is substantially quadrilateral. The substantially quadrilateral shape has a first side and a second side, which are substantially parallel to each other. In the plan view, from the first surface side of the sealed part, the magnetization direction of the pinned layer, in a state in which the external magnetic field is not applied on the magnetoresistive effect element, is inclined with respect to an approximately straight line found through the least squares method using a plurality of points arbitrarily set on the first side.
