PROBLEM TO BE SOLVED: To prevent deterioration of a magnetic device due to damage introduced by a magnetic tunnel junction. SOLUTION: The magnetic device comprises a lower electrode 28 provided with a recess 26 in the upper surface, a magnetic tunnel junction layer 30 formed on the inner surface of the recess in the lower electrode and on the lower electrode on the outside of the recess, and including a tunnel barrier layer and a magnetization fixed layer and a magnetization free layer sandwiching a tunnel barrier layer vertically, and an upper electrode 40 formed on the magnetic tunnel junction layer so as not to reach the side surface of the magnetic tunnel junction layer.
