Claim 0:
1. A magnetic sensor comprising:
a magnetic sensor chip that includes a magnetoresistive effect element; and
a die having a mounting surface for mounting the magnetic sensor chip;
wherein the magnetoresistive effect element includes a free layer, a magnetization direction of the free layer which can change in accordance with an external magnetic field, and a pinned layer, a magnetization direction of the pinned layer which is fixed;
a shape of the die in a plan view from the mounting surface side is substantially quadrilateral;
the substantially quadrilateral shape has a first side and a second side, which are substantially parallel to each other, and a third side and a fourth side, which are substantially parallel to each other and that intersect the first side and the second side; and
in the plan view from the mounting surface side of the die, 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;
in the plan view from the mounting surface side of the die, the magnetization direction of the free layer, in a state in which the external magnetic field is not applied on the magnetoresistive effect element, is substantially orthogonal to the magnetization direction of the pinned layer.
