PROBLEM TO BE SOLVED: To provide a weighing device for measuring an article load highly accurately in a short time from an article loading/removing timing by preventing to the utmost a vibration having a large amplitude or an irregular vibration generated when the article is loaded on or removed from a load loading part, from having an influence on a transient response of a weighing signal. SOLUTION: A load cell 2 has a characteristic wherein, when the article is loaded from above, the load cell 2 is vibrated in the vertical direction of a static load position corresponding to the static weight of the article lower than an unloaded position, and simultaneously the vibration is gradually converged to the static load position. When the article is loaded on the load cell 2, a stopper 18 is brought into contact with the load cell 2 at a slightly lower position than the unloaded position, and after finish of article supply, the load cell 2 is displaced to the static load position at slower speed than vibration speed of the load cell 2, and thereafter the stopper 18 is put into the noncontact state with the load cell 2.
