There is provided a biosensor measurement system which can output a highly-precise measurement result even when an impact such as falling of the sensor occurs or the biosensor is an exposed sensor. An abnormal waveform detection electrode is provided in addition to electrodes for quantitative determination of a target substance. Therefore, when an impact is caused by such as falling of the sensor in a halt period where no voltage is applied in a voltage application algorithm, the abnormal waveform detection electrode can detect the impact. Further, also an exposed sensor can be detected by the abnormal waveform which is detected by the abnormal waveform detection electrode.
