Abstract
A manufacturing method for a magnetoresistive element includes: a step of forming a stack; a step of forming an insulating film to cover the stack; a step of forming an initial magnetic layer to cover the stack and the insulating film so that a thickness of the initial magnetic layer in a first direction is greater than a thickness of the stack in the first direction; a step of forming an organic material film on the initial magnetic layer; and an etching step of etching a part of the initial magnetic layer and the organic material film by ion beam etching so that the initial magnetic layer becomes a pair of magnetic layers.
