Abstract: The present invention provides a powder material supply device, wherein a powder and/or granular material supplied to an inner cylinder 4 is pushed outward through a gap G by rotation of a rotary blade 8 and discharged from an outlet 18, the outlet 18 being arranged to satisfy the relation of L1?G×(1/tan X°) (wherein X° is an angle of response of the powder and/or granular material), with the shortest distance from the outer end of outlet 18 to a point directly below the inner circumference of the inner cylinder 4 on the bottom plate 2a being L1 (mm), and the dimension of the gap being G (mm). With such a powder material supply device, a fixed amount of powder and/or granular material mixing two or more kinds of powder and/or granular material can be supplied while suppressing a fluctuation in the content ratio.
