PROBLEM TO BE SOLVED: To provide an electronic balance which can surely execute a temperature correction without a time lag to a zero drift correction coefficient with respect to an ambient temperature change, while carrying out the temperature correction to both a span coefficient and the zero drift correction coefficient by an output of one temperature sensor, and can surely suppress a drift of a zero point. SOLUTION: The electronic scale has a load-judging means 10c for judging the presence/absence of a load to a measurement pan 2, and a load data change rate judging means 10d for judging whether a change rate of load data from a load-detecting part 8 exceeds a specified rate or not. When no load is applied and the change rate of the load data exceeds the specified rate, temperature data from a temperature sensor 9 is corrected to a direction in which a change of the temperature data is emphasized and then provided to a temperature correction for a zero drift correction coefficient. A time lag in output of the temperature sensor 9 to an ambient temperature is thus eliminated, and a shift of a zero point is surely suppressed.
