1. A magnetic sensor comprising: an element portion that is elongate and that exhibits a magnetoresistive effect;
the element portion is non-oval and is arranged in an imaginary ellipse, wherein the imaginary ellipse has a major axis that connects both ends of the element portion with regard to a direction of a long axis thereof to each other and a minor axis that connects both ends of the element portion with regard to a direction of a short axis thereof to each other, as viewed in a direction that is perpendicular both to the short axis and to the long axis of the element portion, wherein
a width of the element portion with regard to the direction of the short axis thereof decreases from a middle position of the element portion with regard to the direction of the long axis thereof toward both ends of the element portion with regard to the direction of the long axis thereof as a distance from the middle position increases, and
a rate of a change in the width of the element portion in the direction of the long axis increases from the middle position toward the both ends of the element portion with regard to the direction of the long axis thereof as a distance from the middle position increases.
