It has a calculation function that calculates the amount of error due to the span change due to the temperature change with respect to the tare weight load, and a calculation function that calculates the amount of error due to the span change due to the temperature change with respect to the tare weight. At the time, the load value detected by the load cell 1 is automatically corrected based on the amount of error caused by the temperature change detected by the temperature sensor 2 and the span change with respect to the load of the object to be weighed. 1. A temperature-based error correction device for a load cell scale, characterized in that it is provided with a correction calculation circuit 3 having a calculation function for outputting a load value.゛
