Abstract

The manufacturing method provided by the present invention provides a powder material substantially comprising Ag—Pd core-shell particles consisting of Ag core particles containing silver as a principal constituent element and a Pd shell containing palladium as a principal constituent element covering at least part of the surface of the Ag core particles, wherein hydroquinone and/or a quinone is attached to the surface of the Ag—Pd core-shell particles. Typically, when the powder material is in a dispersed state in a specific medium, a Z average particle diameter (D) based on the dynamic light scattering (DLS) method is 0.1 μm to 2 μm, and the polydispersity index (PDI) based on the dynamic light scattering method is 0.4 or lower.
