The application provides a preparation method of low-resistance flaky silver-palladium alloy powder and conductive paste, and belongs to the field of preparation of precious metal powder materials. The preparation method of low-resistance flaky silver-palladium alloy powder comprises the following steps: (1) mixing a silver salt solution, a palladium salt solution and a reducing agent solution to perform a reduction reaction, so as to obtain silver-palladium alloy powder; (2) mixing the silver-palladium alloy powder, a dispersion liquid and a ball-milling dispersant, and then performing ball-milling, so as to obtain flaky silver-palladium alloy powder; the milling balls used in the ball-milling include one or more of steel balls, zirconium dioxide balls and agate balls. The flaky silver-palladium alloy powder is prepared by adopting the mode of "alloying first and then ball-milling", the two key links of "alloying" and "flaky" can be independently optimized, the uniformity and the controllability of the morphology of the powder are improved at the atomic level, the prepared flaky silver-palladium alloy powder has good dispersibility and a smooth surface, and has a resistance superior to that of spherical alloy powder, spherical mixed powder and flaky mixed powder.
