(57) [Summary] (Modified) [PROBLEMS] To provide a circuit material having excellent bending resistance and connector resistance in a membrane circuit. A conductive paste comprising a conductive powder (A), a cellulose derivative (B) and another organic resin (C) as a binder. The conductive powder (A) used in the present invention preferably contains silver powder alone or silver powder in an amount of 60% by weight or more, particularly 70% by weight or more, and more preferably 80% by weight or more. As the cellulose derivative (B), For example, cellulose acetate butyrate (CAB), Cellulose acetate (CA) and the like can be mentioned. The type of the other organic resin (C) to be blended is not limited, but the number average molecular weight is preferably 3,000 or more. |
