Abstract
A magnetic domain wall motion element includes a first ferromagnetic layer, in-plane wiring, and first, second and third via wirings. A position of the in-plane wiring in a stacking direction is different from that of the first ferromagnetic layer. The first via wiring connects the first ferromagnetic layer and in-plane wiring. The second via wiring is connected to the in-plane wiring at a different position from the first. The third via wiring is connected to the in-plane wiring at a different position from the first and second. When positions of the second and the third via wirings are projected on an axis passing through a center of the first via wiring when viewed in the stacking direction and extending in a second direction, the first via wiring is interposed between projection points of the second and third via wirings to the axis in the second direction.
