Abstract
A magnetoresistive element includes an insulating layer formed between electrode layers, and the electrode layers are formed on a multilayer film so as to be in contact with the sides of the insulating layer. The thickness of the electrode layers can therefore be kept thick even at front end faces and a sensing current can flow into the multilayer film always at a constant level.
