은 미립자는, 입경이 65 nm 이상, 80 nm 이하이며, 표면에 탄화수소 화합물로 이루어지는 박막을 가진다. 은 미립자는, 시차열 분석에 있어서의 발열 피크 온도가 140℃ 이상, 155℃ 이하이다. 은 미립자는, 온도 100℃, 1시간의 소성 후의 입경을 d로 하고, 소성 전의 입경을 D로 할 때, (d-D)/D(%)로 나타내는 입자 성장률이 50% 이상인 것이 바람직하다. 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.
