The present invention provides a method for producing metal particles capable of suppressing the average particle size from becoming 50 nm or more. An acidic reaction solution containing metal ions, titanium trichloride as a reducing agent, a complexing agent, and a dispersant is adjusted to be alkaline, and the reaction solution is stirred to precipitate metal particles. . As the complexing agent, at least one of malic acid, malate, gluconic acid and gluconate is used. [Selection] Figure 1 |
