Copper powder for conductive paste, and conductive paste

A copper powder for a conductive paste contains 0.1 atm%-10 atm% of Si (silicon) and 0.1 atm%-10 atm% of In in the particle.  It is preferable that the copper powder for a conductive paste contains 0.1 atm%-10 atm% of Ag (silver) in the particle.  It is also preferable that the copper powder for a c...

Summary:A copper powder for a conductive paste contains 0.1 atm%-10 atm% of Si (silicon) and 0.1 atm%-10 atm% of In in the particle.  It is preferable that the copper powder for a conductive paste contains 0.1 atm%-10 atm% of Ag (silver) in the particle.  It is also preferable that the copper powder for a conductive paste contains 0.01 atm%-0.5 atm% of P (phosphorus).  The ratio of Si/In (atm ratio) is preferably 0.5-5.  The copper powder for a conductive paste is preferably manufactured by an atomization method.
