Abstract: Provided is a large weight scale capable of weighing a to-be-weighed subject sitting in a wheelchair, including a rectangular weighing base on which the to-be-weighed subject gets on, weighing sensors disposed at four corners of the weighing base, and a control unit configured to perform arithmetic operations based on output values of the weighing sensors, wherein the large weight scale includes a bedsore detecting unit configured to detect and make a notification of the possibility of the to-be-weighed subject in a wheelchair developing a bedsore based on a first sum value of output values of a pair of the weighing sensors disposed on a left side of the weighing base, a second sum value of output values of a pair of the weighing sensors disposed on a right side of the weighing base, and a third sum value of output values of all of the weighing sensors.
