In the measure continuously possible body fluids component measurement system, compaction of suspension time is assured. The body fluids component measurement system which relates to this invention to be detained on the skin of the suffering inspection person, installation and removal be installed possibly in the sensor section 110 which measures the specified body fluids component which is included in the body fluids of the said suffering inspection person, and sensor section 110 to calculate blood glucose value on the basis of the measurement data which was measured in sensor section 110 the said the transmission section 120 which transmits the blood glucose value which was calculated to indicatory department 130 and, have, transmission section information of the identification in order to establish the communication with 120 and indicatory department 130 to be stored in sensor section 110, as for aforementioned transmission section 120,When activating, in order to establish the communication with the indicatory department 130, making use of the information of the identification which it reads out from sensor section 110, it features that it is constituted.連続測定可能な体液成分測定システムにおいて、中断時間の短縮を図る。本発明に係る体液成分測定システムは、被検者の皮膚に留置され、該被検者の体液に含まれる所定の体液成分を測定するセンサ部110と、センサ部110に着脱可能に取り付けられ、センサ部110において測定された測定データに基づいて血糖値を算出し、該算出した血糖値を表示部130に送信する送信部120と、を備え、センサ部110には送信部120と表示部130との間の通信を確立するための識別情報が格納されており、前記送信部120は、起動時に、センサ部110より読み出した識別情報を用いて、表示部130との通信を確立するよう構成されていることを特徴とする。
