PROBLEM TO BE SOLVED: To provide a fine-grain gun equipment where high pressure gas is not needed, capable of precisely regulating force imparted to metal fine grains and capable of making operation for applying metal fine grains to film needless. SOLUTION: When this fine-grain gun equipment has fine grains made of a metal or the like, an adsorbing stand 26 made of a porous material for adsorbing fine grains, a sliding member 13 coupled with the stand 26, a weighting member 43 for imparting impact to the member 13 so as to make it slide, a retaining means for retaining the member 43 in the upper part, a decompressing means enabling a cavity 57 below the member 43, into which the member 43 is moved, to be decompressed, a member 13-receiving vessel for sliding the member 13, and a pedestal installed in the vessel. A vacuum vessel coupled with the cavity 57 through a coupling tube 18 for stabilizing the vacuum pressure of the cavity 57 so as to have constant value is additionally installed, a nozzle for making a gene-including liquid adhere so as for genes adhere to the fine grains below the sliding member-receiving vessel is also additionally set up and minute ruggedness is formed on the surface of each fine grain.
