A magnetoresistive element includes, in plan view, an element section and an extension region extending from an end portion of the element section; and an insulation layer is formed on the element section and the extension region. A contact hole having a recessed shape, penetrating through the insulation layer, and extending at least to the extension region is formed; an electrode pad is formed in the contact hole; a surface of the electrode pad is exposed to outside; and the electrode pad is electrically connected to the extension region. The element section and the extension region are integrally formed so as to have an identical layer configuration employing a magnetoresistive effect in which electrical resistance varies in response to external magnetic fields.
