PURPOSE: A manufacturing method of silver nanoparticle using ionic liquid is provided to manufacture uniform sized silver nanoparticle using silver precursor and ionic liquid without separate reducing agent and stabilizer. CONSTITUTION: A manufacturing method of silver nanoparticle using ionic liquid comprises the following steps: mixing hydrophilic organic solvent solution including silver precursor with hydrophobic ionic liquid; mixing hydrophobic organic solvent solution including silver precursor with hydrophilic ionic liquid; and ultrasonic wave processing the mixture. The silver precursor is either silver complex or silver halide. The hydrophobic ionic liquid includes one of organic cation which is selected from dialkylimidazolium, alkylpyridinium, quaternary ammonium, and quaternary phosphonium, and one of negative ion which is selected from an anionic group including SbF6-, PF6-, NTf2- (Trifluoromethanesulfonyl)amide, etc. The hydrophilic ionic liquid is one of organic cation which is selected from dialkylimidazolium, alkylpyridinium, quaternary ammonium, and quaternary phosphonium, and one of negative ion which is selected from an anionic group including NO3-, BF4-, AlCl4-, Al2Cl7-, AcO-, TfO- (Trifluoromethanesulfonate), (CF3SO2)2N-, and CH3CH(OH) CO2-(L-lactate), etc.
