Zusammenfassung:	The present invention provides a nickel-plated heat-treated steel sheet having excellent corrosion resistance and a method for manufacturing the same. According to the present invention, the nickel-plated heat-treated steel sheet has an amount of remaining Ni of 0.1 wt% or more to less than 30 wt% of the total amount of Fe and Ni when a Ni-Fe alloy layer is analyzed using energy dispersive spectrometer (EDS) or electron probe x-ray microanalyses (EPMA) after the alloying heat treatment of a nickel plating layer and base Fe, and completely removing the pure Ni remaining on the Ni-Fe alloy layer. 본 발명은 니켈 도금층과 소지 Fe와의 합금화 열처리 후 Ni-Fe 합금층 위에 잔재하는 순 Ni를 완전히 제거한 후 EDS(Energy Dispersive Spectrometer) 혹은 EPMA(Electron Probe X-ray Microanalyses)를 이용하여 Ni-Fe 합금층을 분석하였을 때 잔존하는 Ni의 량이 Fe와 Ni 전체량의 0.1중량% 이상 내지 30중량% 미만인 것을 특징으로 하는 내식성이 우수한 니켈도금 열처리 강판 및 그 제조 방법을 제공한다.
