| Zusammenfassung: | PURPOSE:To prevent the expansion of corrosion in the interface between ferromagnetic film and protective coat in a magnetoresistance element having a trimming part. CONSTITUTION:In a magnetoresistane element comprising a protective coat 11 formed on a ferromagnetic film 8 and a trimming part 21 provided for adjusting values of resistance, a corrosion resistant film 22 composed of material satisfactorily bonded to both ferromagnetic film 8 and protective coat 11 is formed between the ferromagnetic film 8 and protective coat 11, at least in the vicinity of the trimming part 21. |
