FINE METAL PARTICLE-CONTAINING COMPOSITION

摘要

A fine silver particle-containing composition includes a large number of fine silver particles 2 and a coating layer 4 that covers a surface of each silver particle 2. The silver particle 2 is a so-called nano particle. The silver particle 2 has a scale-like shape. The coating layer 4 consists of an organic compound. The organic compound binds to the silver particle 2. The organic compound suppresses aggregation of the silver particle 2. The composition is in a cake form. A weight ratio of the organic compound with regard to the total amount of the composition is not lower than 2% but not higher than 15%.
