PROBLEM TO BE SOLVED: To provide a powder feeder which can easily adjust volume of a nozzle for filling with powder with high precision, and improve productivity.SOLUTION: A partitioning plate 4 formed by laminating a movable plate 41 and a substrate 42 is arranged between a powder feeding part 2 in which powder is input and a fixed plate 5 with a powder feeding passage 51 arranged. A nozzle part 3 is formed by mounting a cylindrical nozzle 44, which follows the movable plate 41 and displaces, on a fitting hole 31 formed on the powder partitioning plate 4. A moving amount of the movable plate 41 in a thickness direction is adjusted by an adjusting part 6 to vary volume of the nozzle. The nozzle part 3 moves from a position communicating to a powder discharge port 22 on a bottom surface of the powder feeding part 2 to a position communicating to the powder feeding passage 51, and feeds a predetermined amount of powder to a powder filling part 52. |
