A laminate may include the following layers in order: a transparent substrate, a first dielectric layer, a silver layer, a light-absorbing layer, a first barrier layer, and a second dielectric layer. The first dielectric layer may be in contact with the transparent substrate, and a single silver layer may be present in the laminate between the first dielectric layer and the second dielectric layer.

Laminate

To provide a process for producing a reliable substrate in good yield, by suppressing bleeding of boric acid from a green sheet comprising a powder of borosilicate glass to improve printability of a conductive pattern thereby to prevent disconnection. A process for producing a substrate which comprises firing a green sheet comprising a powder of borosilicate glass, wherein the powder is one prepared by holding borosilicate glass before pulverization, at a temperature higher by at least 30&#xb0; C. than the glass transition temperature and lower by at most 50&#xb0; C. than the softening point of the borosilicate glass for at least 3 hours in the atmosphere, followed by pulverization.
