PROBLEM TO BE SOLVED: To provide a metal powder capable of being used for a conductive paste having a sufficient electric conductivity even when the conductive paste contains a less amount of the metal powder. ! SOLUTION: A silver-coated copper powder comprises: a dendritic projection silver-coated copper powder made by coating, with silver, a dendritic projection copper powder constituted of grains each having a structure having one stem part serving as a main axis and a plurality of branches branched from the stem part; a spinous silver-coated copper powder made by coating, with silver, a spinous projection copper powder constituted of grains each having a structure that a plurality of grains of a dendritic projection copper powder are entangled with each other and coagulated so as not to separate, or a structure having a central part as a core and branches extended from the core radially; and a bar-shaped silver coated-copper powder made by coating, with silver, a bar-shaped copper powder constituted o |
