Abstract
In the present invention, a fine silver particle has a particle diameter of 65-80 nm and has, on the surface of the particle, a thin film comprising a hydrocarbon compound. The fine silver particle has an exothermic peal temperature of 140-155° C. in differential thermal analysis. If d denotes the particle diameter after firing at a temperature of 100° C. for one hour and D denotes the particle diameter before firing, it is preferable for the fine silver particle to have a particle growth rate, as represented by (d−D)/D (%), of 50% or higher.
