Claim:
1. A current-perpendicular-to-plane magneto-resistance effect element, comprising: a substrate comprising at least one of a surface-oxidized Si substrate, a silicon substrate, a glass substrate, and a metal substrate; an orientation layer formed on the substrate to texture Heusler alloy into a (100) direction; a lower ferromagnetic layer and an upper ferromagnetic layer that each comprises a polycrystalline thin film of a Heusler alloy textured into a (100) direction, and that are each formed on the orientation layer; and a spacer layer sandwiched between the lower ferromagnetic layer and the upper ferromagnetic layer, wherein the orientation layer comprises at least one of MgO, TiN, and NiTa alloys, thereby improving a variation of the electric resistance per unit area of the element, compared with that of a (110) textured polycrystalline element not using an orientation layer.
