<P>PROBLEM TO BE SOLVED: To provide a high-temperature calcination type silver paste in which a conductive pattern with excellent precision can be formed by an intaglio offset printing method or the like, and the conductive pattern with superior conductivity and small surface resistance can be formed by a short time baking, and to provide an electromagnetic wave shield which has a shield pattern formed using the high-temperature calcination type silver paste and has superior transparency and electromagnetic wave shield characteristics. Ž<P>SOLUTION: The high-temperature calcination type silver paste contains silver powders with average particle size of 0.1 μm or more and 3 μm or less, silver nano-particles with average particle size of 10 nm or more and 200 nm or less, glass frit, a binder resin, and solvent, and the ratio of the silver nano-particles occupied in a total quantity of the silver powders and silver nano-particles is made 1 wt.% or more and 10 wt.% or less. The electromagnetic wave shield has a shield pattern formed on a transparent substrate by an intaglio offset printing method using the high-temperature calcination type silver paste.
