The invention discloses a preparation method for electric conduction flake silver-coated copper powder. The preparation method comprises the steps that the flake copper powder is washed and activated;crystal points on the surface of the copper powder are formed; silver is subjected to deposition to completely wrap the copper powder; and the silver-coated copper powder is firstly washed with water, then washed with ethyl alcohol and finally dried to prepare the electric conduction flake silver-coated copper powder. Compared with an existing preparing technology, the content of the coated silver powder can be very high, the prepared silver-coated copper powder is even in wrapping, exposure into air is avoided, oxidation is not prone to happening, the electric conduction performance is good,and storage is stable.
