An object of the present invention is to suppress the formation of copper oxide in each process of handling a conductive composition such as coating, drying, firing, etc. while containing copper powder, and to have excellent initial conductivity and excellent long-term conductivity. Provide sustainable, conductive materials. A conductive material containing copper powder and a salt of an ascorbic acid derivative represented by the general formula (1). General formula (1) (R1 and R2 are each independently H or a substituted / unsubstituted acyl group; X + is a quaternary ammonium cation or a substituted / unsubstituted imidazole cation) [Selection figure] None |
