ABSTRACT:
A composite substance for forming a conductive paste, comprises a solvent being compatible with an organic component included in the conductive paste, and metal particles wetted by the solvent. The conductive paste comprises an organic binder, the composite substance and an organic solvent mixed with the organic binder and the composite substance. The method for manufacturing the composite substance comprises the step of adding the solvent to undried metal particles having been washed with water, the solvent being compatible with the organic binder included in the conductive paste and incompatible with water so that the water is replaced by the solvent. The method for manufacturing the conductive paste comprises the step of mixing an organic binder and an organic solvent with the composite substance.
