Abstract
A method of weighing an easily chargeable measured object able to remove the effects of static electricity to weigh a measured object by an accuracy of about 0.3 mg continuously with a good work efficiency. When using an electronic scale (10) provided with a weighing platform (11) and a weighing pan (12) able to move vertically by a very small distance with respect to the weighing platform to weight an easily chargeable measured object (14), the measured object is weighed in the state with a conductive frame (13) of a suitable size set on the weighing platform (11) around the weighing pan so as to surround the measured object placed on the weighing pan.
