ABSTRACT:
A magnetoresistance effect device includes: an insulator layer; a first and second ferromagnetic layer laminated to sandwich the insulator layer; a magnetic bias layer laminated with the second ferromagnetic layer; and a connecting section formed discontinuously on a side face of the insulator layer. The connecting section is not interposed between the second ferromagnetic layer and the magnetic bias layer. The connecting section is made of a ferromagnetic material, and electrically connecting between the first ferromagnetic layer and the second ferromagnetic layer. A method for manufacturing a magnetoresistance effect device includes: laminating a first and second ferromagnetic layer to sandwich an insulator layer, and laminating a magnetic bias layer with the second ferromagnetic layer; and forming a connecting section for electrically connecting between the first ferromagnetic layer and the second ferromagnetic layer by discontinuously forming a ferromagnetic material on a side face of the insulator layer.
