... ****This Zn-plated steel sheet is provided with: a steel sheet; a Zn-based plating layer that is disposed on at least one surface of the steel sheet and contains 0.05-60 mass% of Al and Zn; and a chromate-free chemical conversion treatment layer disposed on the Zn-based plating layer, the chemical conversion treatment layer containing 20% by mass or more of a resin, 1-20% by mass of silica particles having an average particle diameter of 5-200 nm, and a pigment containing one or more of Cu, Co, and Fe, and the chemical conversion treatment layer containing chromate in the amount of 0.1-15 g/m2 per surface of the Zn-based plating layer by using CIE1976 (L *, a *, b *, c *). B *) is from-30 to-2 (inclusive) when the appearance is evaluated in a color space, the 60-degree specular gloss Gs (60 degrees) specified in JIS Z8741: 1997 is from 50 to 200, and a metallic appearance is exhibited.

... ********This Zn-plated steel sheet is provided with: a steel sheet; a Zn-based plating layer that is disposed on at least one surface of the steel sheet and contains Al and Zn; and at least one chromate-free chemical conversion treatment layer disposed on the Zn-based plating layer and having an adhesion amount on one surface of 0.1-15 g/m2, the chemical conversion treatment layer containing a resin and a yellow colorant, b * being 2-60 (inclusive), b */a * being-3-3 (inclusive), 60 degree specular gloss Gs (60 degrees) being 50-200, and b */a * being-3 (inclusive) when the appearance is evaluated using a CIE 1976 (L *, a *, b *) color space. When L *, which is obtained when light is incident toward the surface at an angle of 60 degrees with respect to the surface of the chemical conversion treatment layer and light reflected by the surface is received at an angle of 135 degrees with respect to the surface, is denoted as L * 1, and L *, which is obtained when light is incident toward the ...
