Conductive compositions and solar cell

An object of the present invention is to provide a solar cell using the conductive composition capable of forming a low electrode or the like having a volume resistivity and it collecting electrode. Conductive composition of the present invention, copper powder and (A), a fatty acid silver salt (B), a conductive composition having a thermosetting resin (C), the heat of the fatty acid silver salt (B) the difference between the decomposition peak temperature and the thermal decomposition starting temperature is not less 40 ° C. or more, the content of the fatty acid silver salt (B) is, in terms of the amount of silver produced from the organic silver salt (B), copper powder (a ) from 20 to 100 parts by weight per 100 parts by weight, a conductive composition.
