Abstract

See full text

Copper particles are provided that each include a core particle made of copper and a coating layer that coats the surface of the core particle, wherein the coating layer is made of a copper salt of an aliphatic organic acid. It is also preferable that the copper particles have an infrared absorption peak in a range of 1504 to 1514 cm−1 and no infrared absorption peak in a range of 1584 to 1596 cm−1. It is also preferable that, in thermogravimetric analysis of the copper particles, the temperature at which the ratio of the mass loss value to the mass loss value at 500° C. reaches 10% is from 150° C. to 220° C. A method is also provided for producing copper particles, the method including bringing core particles made of copper into contact with a solution containing a copper salt of an aliphatic organic acid to thereby coat the surface of the core particles.
