Abstract

Provided are highly reliable silver-coated conductive particles, which are prevented from an occurrence of migration, the silver-coated conductive particles in which: a tin layer is formed on a surface of each spherical base particle, and a silver plating layer is formed on a surface of the tin layer, and a surface of the silver plating layer is coated with a water repellent layer: the water repellent layer includes an organic sulfur compound that is mainly composed of a sulfide compound or a surfactant such as polyoxyethylene ethers: and a molded body that is formed by pressing the silver-coated conductive particles at a pressure of 14.7 MPa has a contact angle with water of 125 degree or more.
