PROBLEM TO BE SOLVED: To smoothly convey a poor flowability powder and surely supply/charge it to a next step such as a molding die of a powder compression molding device by accurately dispensing a required constant amount of powder. SOLUTION: This constant quantity feeder for the poor flowability powder comprises a powder supply part 10 for conveying a powder, a powder dispensing part 12 for dispensing a constant quantity of the powder conveyed, and a preliminary pressurizing part 14. The powder supply part has a powder box 24 and a sieve mesh 26 on a powder conveying trough 20, and conveys the poor flowability powder after being loosened off by the sieve mesh vibrating the coagulated poor flowability powder. The powder dispensing part controls the position of a rod 32 in a cylinder 30 by a pulse motor 36, regulates the amount of the powder contained in a cylinder hole 34, regulates the specified amount of the powder contained in the cylinder hole 34, and dispenses a specified amount of powder by a scraper mechanism.
