摘要

PROBLEM TO BE SOLVED: To provide a biosensor serving also as a punctual needle and a body fluid measurement device using it capable of dissolving the troblesomeness of a measuring operation, pursuing low invasiveness by the fact that a required inspection sample amount is a fine amount and being used for medical measurement such as blood sugar measurement. SOLUTION: This biosensor serving also as the punctual needle is provided with the hollow needle 2 of an electrically conductive hollow punctual member having a sharp tip, a measurement electrode 4 covered with an insulating coating film 3 is arranged inside the hollow needle 2 and an enzyme reaction layer 1 is installed so as to cover the cross section of the measurement electrode on a tip part side. The biosensor is electrically connected and this measurement device for measuring specified components in an inspection sample is manufactured.
