摘要： One object of the present invention is to provide metal fine particles which have selective wavelength absorption characteristics in a wavelength region from visible light to near infrared light, and have sharp absorption characteristics, and influences little the surrounding wavelength, and therefore, they yield tones having high chroma. The present invention provides a production method for producing metal fine particles by reducing metal ions in an aqueous solution containing a surfactant, wherein an aspect ratio of the metal fine particles is controlled by performing the reduction reaction while adjusting a solution temperature.
