If the reaction molar ratio of the silver nitrate to hydrochloric acid is 1:1-1:0.06, silver chloride(AgCl) nano particle aggregate containing silver (Ag) nano particle will be formed. If reaction molar ratio of the silver nitrate to hydrochloric acid is 1:0.05-1:0.01, silver (Ag) nanowire will be formed. A manufacturing method of the silver chloride nano aggregate additionally includes a step of reducing the AgCl aggregate using a reducing agent after AgCl aggregate formation.
