Abstract
This silver-coated spherical resin includes: a spherical resin; and silver coated on a surface of the spherical resin, wherein an amount of the silver is in a range of 2 to 80 parts by mass with respect to 100 parts by mass of the silver-coated spherical resin, and a crystallite diameter of the silver measured by X-ray diffractometry is in a range of 18 to 24 nm. This method for producing a silver-coated spherical resin includes: a process of subjecting a spherical resin to a pretreatment using an aqueous solution of a tin compound; and a subsequent process of subjecting the spherical resin to an electroless silver plating using a reducing agent, wherein, during the pretreatment, a temperature of the aqueous solution of the tin compound is set to be in a range of 20 to 45° C.
