The preparation method of the organic silver colloid comprises the following steps: dissolving an inorganic silver salt solid in water to obtain a silver precursor solution; diluting an organic complexing agent with water to obtain an organic complexing solution; dissolving a stabilizer in water to obtain a stabilizer solution; and mixing the stabilizer solution, the organic complexing solution and the silver precursor solution, and carrying out complexing reaction to obtain the organic silver colloid. The invention further discloses the organic silver colloid, the organic silver colloid comprises the organic silver colloid particles and the stabilizer, and in the organic silver colloid, the silver content is 0.01-0.2 mol/L, preferably 0.01-0.05 mol/L. The organic silver colloid prepared through the method is high in stability, stable and uniform in colloid color and stable and uniform in viscosity, and the upper liquid level and the lower liquid level have no viscosity difference. 公开一种有机银胶体制备方法，包括：将无机银盐固体溶于水
