Abstract

An object of the invention is to provide a foreign substance removing device that is effective even for highly adhesive powder. Therefore, the foreign substance removing device of the invention includes: a substrate on which powder is to be placed; and a classification unit configured to classify powder to be collected and a foreign substance particle to be removed. The classification unit includes a classification mesh, a vibration unit that vibrates the substrate and/or the classification mesh, and a pressing unit that presses the classification mesh against the powder. In this way, by pressing the mesh against the powder and vibrating the powder, agglomerates of the powder can be de-agglomerated, a classification can be performed at the same time, and thus a foreign substance can be removed even for highly adhesive powder.
