Abstract
A stator includes a magnetic body having a through-hole, a magnetoresistive portion disposed around the through-hole to generate a magnetic pole around the through-hole in a case where a coil is excited, and a non-magnetic portion disposed at a position different from a position of the magnetoresistive portion around the through-hole by means of thermal melting, and formed to have lower magnetic permeability than the magnetic body.
