<p>A gas sensor material comprising a carbon mixture or metal-containing carbon mixture is obtained as an evaporation material produced by arc discharging obtained by causing a D.C. or A.C. current, which has a current density of 0.8 to 3.5 A/mm2 on a discharge surface of an electrode, to flow through a carbon electrode or a metal-containing carbon electrode in an inert gas at a pressure of 0.1 to 600 Torrs.</p> |
