Abstract:
A magnetoresistive device, comprising:a magnetoresistive film extending in a first direction and having side-end faces;a magnetic bias film for applying magnetizing bias field extending in the first direction and having side-end faces;a first insulating film made of an electrically insulating material for magnetically and electrically isolating the magnetoresistive film from the magnetic bias film, the first insulating film being sandwiched between the magnetoresistive film and the magnetic bias film and having side-end faces;lead electrodes placed to be electrically connected to at least the magnetoresistive film; anda base body having a supporting surface which extends in the first direction so as to support the magnetoresistive film, the first insulating film, the magnetic bias film and the lead electrode layer; wherein:the side-end faces of the magnetoresistive film are sloping at 10 to 30 degrees from the supporting surface of the base body; andthe side-end faces of both of the magnetic bias film and the first insulating film are substantially perpendicular to the supporting surface of the base body.
