A load cell includes a horizontal upper beam; a lower beam extending parallel with the upper beam; a fastening section connecting one end of the upper beam to the lower beam and is fastened to a stationary object; a movable section which connects the upper beam and the lower beam and is displaced vertically by a load applied to the movable section 5; and a cylindrical stopper having a circular cross-section. The fastening section has a first circular hole. The movable section has a second circular hole concentric with the first circular hole. A base end portion of the stopper is fastened to the first circular hole and a tip of the stopper member 7 is located at an inner side of the second circular hole such that there is a space of a specified width between the tip and an inner surface of the second hole.
