To obtain a glass sheet with a dark color conductor having ≤30 brightness index L'.

A conductive paste containing a conductive material powder such as a silver powder, and a low melting point glass powder, an org. varnish and a silicon (Si) powder is prepared. The prepared conductive paste is applied on the surface of a glass sheet by screen printing to form three conductive stripes each comprising a line of 1.0 mm width and about 200 mm length and 10 mm squares attached to the both ends of the line. Then the pattern is dried at 120°C for 10 min and fired at 680°C for 5 min in an electric furnace to produce a glass sheet with a conductive body. The brightness index L' of the square pattern is ≤30 by measuring through the surface of the glass where the conductive paste is not printed or fired.
