1. A nickel-plated stainless steel plate, comprising:
a stainless steel base plate; and
a nickel (Ni) plating layer formed on at least one surface of the stainless steel base plate by electroplating,
wherein the stainless steel base plate contains, based on its total weight, C at about 0.001 wt % to about 1.5 wt %, Si at more than 0 wt % to about 2.0 wt %, Mn at about 0.1 wt % to about 2.5 wt %, P at more than 0 wt % to about 0.5 wt %, S at more than 0 wt % to about 0.3 wt %, Cr at about 8 wt % to about 20 wt %, and the remainder being Fe and inevitable impurities, and
the nickel (Ni) plating layer includes a strike plating layer and a main plating layer containing a first plating layer and a second plating layer,, in which
(i) the strike plating layer, the first plating layer, and the second plating layer are sequentially laminated on the one surface of the stainless steel base plate;
(ii) the strike plating layer has a thickness of about 0.3 μm to about 0.5 μm;
(iii) the first plating layer, having a thickness of about 0.5 μm to about 2.5 is both an electrolytic nickel plating layer and a matte plating layer; and
(iv) the second plating layer, having a thickness of about 0.3 μm to about 1.5 is both an electrolytic nickel plating layer and a semi-bright plating layer.
