Abstract
There is provided a method for efficiently manufacturing metal nano particles without condensing laser beams by using a lens etc. In this method, first, metallic foil pieces, which are a starting material, are dispersed in a dispersion liquid. Next, laser beams are irradiated directly to the metallic foil pieces without providing a condensing means, by which many metal fine particles are yielded. The particle diameters of the metal fine particles obtained can be controlled to sizes from nano particles to submicron particles by utilizing the relationship between the shape (especially thickness) of the metallic foil piece which is a starting material and the absorbed energy of the laser beam.
