摘要：
A magnetoresistive effect element includes: a first ferromagnetic layer; a second ferromagnetic layer; and a non-magnetic layer provided between the first ferromagnetic layer and the second ferromagnetic layer, wherein the non-magnetic layer includes a first layer and a second layer, and wherein a lattice constant α of the first layer and a lattice constant β of the second layer satisfy a relationship of β−0.04×α≤2×α≤β+0.04 ×α.
