Provided is a silver-coated copper powder which can be utilized as an electrically conductive paste and an electromagnetic wave shield. A silver-coated copper powder has a dendritic shape having a linearly grown main stem and a plurality of branches separated from the main stem, the main stem and the branches are constituted as flat plate-shaped copper particles having a cross-sectional average thickness of from 0.02 μm to 5.0 μm to be determined by scanning electron microscopic (SEM) observation gather, the surface of the copper particles is coated with silver, the average particle diameter (D50) of the silver-coated copper powder 1 is from 1.0 μm to 100 μm, and the maximum height in the vertical direction with respect to the flat plate-shaped surface of the copper particles is 1/10 or less with respect to the maximum length in the horizontal direction of the flat plate-shaped surface of the copper particles. |
