Abstract: Provided is a weighing apparatus that enables occurrence of an abnormality to be noticed. A weighing apparatus includes a rectangular weighing base, weighing sensors disposed at four corners of the weighing base, a control unit configured to calculate a weighed value of a to-be-weighed object on the weighing base based on outputs of the weighing sensors, and an abnormality detection means configured to detect occurrence of an abnormality based on output values of the weighing sensors, and detects occurrence of an abnormality by comparing a sum of output values of a pair of weighing sensors disposed on one side of the weighing base among the weighing sensors with a sum of past output values of the pair of weighing sensors.
