Abstract
A magnetic storage device which enables stable operation at the time of recording information into MRAM and the stable retention of recorded information. The die of the magnetic storage device has a substrate, first and second wirings, a magnetic storage element and a first magnetic shielding structure. The first magnetic shielding structure is formed to cover the magnetic storage element in a plan view. Second and third magnetic shielding structures sandwich the die in a thickness direction. A lead frame member has the die mounted thereon and contains a ferromagnetic material. The lead frame member overlaps with only part of the die in a plan view.
