PROBLEM TO BE SOLVED: To provide a filtering member and a washing method for metal particulates capable of surely filtering and washing the metal particulates whose grain size is less than 0.2μm with high productivity. SOLUTION: A filter plate 4 has a three-layer structure in which a sheet-like filter 5 whose pore diameter is 0.5-2μm, porosity is 60-80% and thickness is 50-100μm is clamped by a metal sintered filter 6 whose aperture is 0.5-2μm and thickness is 1-3mm and a metal sintered filter 7 whose aperture is 0.5-2mm and thickness is 1-3mm. Then, washing liquid 2 is added into a container in which the powder of the metal particulates of a treating object is charged and is agitated, the powder and the washing liquid are filtered by the filter plate 4, and filtrate is discharged. The powder after recovery is dried. COPYRIGHT: (C)2005,JPO&NCIPI
