A seat load measuring apparatus that can provide an accurate load output even when one or more sensors are exerted with a load in excess of its measurable load is provided. In a first instance, the output of each load sensor is read at Step S11. Subsequently, at step S12, whether or not there is any sensor whereof the output is in excess of the predetermined value is determined. If no output of these sensors is in excess of the predetermined value, it is regarded as normal, and the seat weight is obtained by summation of the outputs of the sensors at Step S13. When the output of any sensor exceeds the predetermined value, it is determined that an offset load is exerted thereon and thus the output of the sensor in question cannot be trusted. Therefore, the seat weight obtained immediately before the output of any of the sensors exceeds the predetermined value is regarded as the seat weight.
