An electrically conductive paste comprises at least an electrically conductive powder, a glass frit and an organic vehicle. The electrically conductive paste is a powder mixture comprising an atomized powder produced by an atomizing method and a wet reduced powder produced by a wet-mode reduction method, and the atomized powder makes up 5 to 40 wt% of the electrically conductive powder. The atomized powder has an average particle diameter of 5.2 to 9 [mu]m, and a chlorine component is incorporated into the electrically conductive powder in an amount of 42 ppm or less. An electrically conductive film 2 can be produced by applying the electrically conductive paste in a line-like form on a glass substrate 1 and then firing the resultant product. Thus, provided are: an electrically conductive paste whereby it becomes possible to prevent the discoloration of a glass substrate or the formation of structural defects, e.g., cracks, in an underlayer for an electrically conductive film; and a glass article, e.g., an an
