The present invention provides a powder filling apparatus which can prevent a screw portion of an auger screw from contacting an inner surface of a metering portion at a funnel lower end portion and besides facilitate the assembling work as well as can be made compact and put into practice at a low cost. The powder filling apparatus comprises a funnel (2) which contains powder, and a circular-cylindrical metering portion (3) provided at a lower end portion of the funnel (2), an auger screw arranged vertically, and a support device (5) which supports the auger screw (4) rotatably. The auger screw (4) has a lower end provided with a screw portion (18) which is arranged within the metering portion (3). The funnel (2) is suspended from the support device (5) and supported thereto and the metering portion (3) has a center axis (3a) made substantially coincident with an axis of rotation (4a) of the auger screw (4).
