Abstract
A magnetic sensor that ensures the height of the yoke and that guides magnetic flux in the direction in which the magnetic field sensing film detects a magnetic field includes a first magnetic field detection element that has a first magnetic field sensing film that detects a magnetic field in a first direction, and a first yoke that includes a first portion that is located on a side of the first magnetic field sensing film with respect to the first direction, and a second portion that is in contact with the first portion in a direction that is orthogonal to the first direction. The average dimension of the second portion in the first direction is larger than the average dimension of the first portion in the first direction.
