Provided are a decorative glass panel having a three-dimensional metal design and a manufacturing method for the decorative glass panel, the method exhibiting enhanced productivity. A decorative glass panel 10 includes: a glass substrate 15; an adhesive layer 11 formed on the glass substrate 15; a non-uniform pattern layer 12 formed on the adhesive layer 11; and a vapor-deposited metal layer 13 formed on the non-uniform pattern layer 12. In the glass substrate 15, a section that is a portion of a back surface of the glass substrate 15 and that is bent from a flat surface section 30 to an upright section 31 forms a curved surface 32. The non-uniform pattern layer 12 has, in a surface facing the vapor-deposited metal layer 13, which is a top surface thereof, a non-uniform pattern formed by depressions 40 and protrusions 41.
