PROBLEM TO BE SOLVED: To provide a powder/granular body measuring device having a high measurement speed and accuracy capable of measuring a powder/granular body having a large target weight. SOLUTION: The measuring device comprises a coarse charging weighing part 10 for weighing the weight W1 of a powder/granular body for coarse charging whose weight is within a predetermined allowable range from the weight Wm for coarse charging that is smaller than the target weight Wt by a predetermined value and for discharging the powder/granular body for coarse charging, and a combination weighing part 20 for discharging a powder/granular body for fine charging. The combination weighing part 20 has a plurality of weighing units 21 each for storing a minimum division unit of powder/granular bodies and weighing the weight thereof. In addition, the combination weighing part 20 selects a combination of powder/granular bodies whose total weight is within a predetermined allowable range from a difference in weight (Wt-W1) between the target weight Wt and the weight W1 of the powder/ granular body supplied from the coarse charging weighing part 10 from optional combinations of powder/granular bodies of each minimum division unit, and discharges the powder/granular bodies from the weighing unit 21 constituting the selected combination for fine charging.
