A memory includes: a magnet including a first and second portions adjacent in a first direction. The first portion has a first dimension in a second direction at a first position at which a dimension of the magnet in the second direction is maximum, the second direction perpendicular to the first direction, the second portion has a second dimension in the second direction at a second position at which a dimension of the magnet in the second direction is minimum, the second dimension smaller than the first dimension, the first portion is continuous to the second portion via a third position between the first and second positions, a curve corresponding to an outer of the magnet extends between the first and third positions, and the curve passes through a side closer to the central axis of the magnet than a straight line connecting the first and second positions.
