A powder filling apparatus adapted to receive a predetermined quantity of powder from a powder hopper in a reception bore formed in a peripheral portion of a rotary board, rotate the rotary board intermittently, and discharge the powder in the reception bore into a powder container, which is placed thereunder, when the reception bore reaches a discharge filling zone, whereby a powder filling operation is carried out. The rotary board (1) is disposed with its axis of rotation <u>C</u> inclined, and each reception bore (8) is provided so that the axis thereof is positioned on an imaginary conical surface (12) having an apex angle theta of 60 DEG -120 DEG and the axis thereof coincides with the axis of rotation <u>C</u>. The powder hopper (6) is disposed at a side portion of an opening (8a) of the reception bore (8) in a vacuum suction unit (9), and a boss (28) for supporting a rotary shaft (34) of an agitator (7) above the powder hopper (6). This apparatus is suitable to be used in a step of filling a container, such as a vial with various kinds of powder including, especially, medical powder, such as an injection powder which demands the accuracy in measuring a filling quantity and the prevention of the mixing of extraneous matter.
