Zusammenfassung:PROBLEM TO BE SOLVED: To produce an Fe-Ni alloy sheet for electronic member having superior press formability and etching characteristic by establishing the hot rolled plate heat treatment conditions improved in yield and hardly causing duplex grain structure. SOLUTION: At the time of producing an Fe-Ni alloy sheet for electronic member, having a composition consisting of, by mass, 34-50% Ni,
