Abstract
Metal nanoparticles according to the present invention have at least a bimodal size distribution in which the ratio obtained by dividing the area of a first peak, which has the smallest median size on the basis of the median size of peaks in the size distribution of the metal nanoparticles, by the total area of all peaks constituting the size distribution meets 0.4-0.8, and are capped with a capping layer containing an organic acid.
