To provide a method and a device for forming the powder in which the thickness of a formed article is approximately fixed, the depth of a charger is not adjusted so often, and if the forming accuracy higher than that of a refractory brick is not required, the forming speed is improved, and the height of the forming device can be minimized.

A cavity block (7) with a cavity (7a) penetrated therethrough below a press (10), and a lower plate (11) therebelow are disposed movably in the horizontal direction, a bottom part of the cavity (7a) of the cavity block is located below a hopper (8) continuous to the press (10) while closing the lower plate (11), a raw material is thrown therein. The cavity block and the lower plate are moved below the press (10), the raw material is compressed in the cavity (7a) by the press (10), the lower plate (11) is retracted and a formed article (15) in the cavity (7a) is taken out below.
