Provided is a production method capable of efficiently producing metal fine particles with a small proportion of spherical metal fine particles and a large proportion of rod-shaped metal fine particles. In a method for producing metal nanorods by an electrochemical reaction in a solution containing a surfactant, an aqueous solution containing a surfactant represented by the following chemical formula (I) is used. Preferably, an aqueous solution containing the surfactant represented by the above (I), the surfactant represented by the following chemical formula (II), and the CTAB represented by the following chemical formula (III) is used.
