BODY-LIQUID SAMPLING CIRCUIT BOARD, ITS MANUFACTURING METHOD AND ITS USING METHOD, AND BIOSENSOR HAVING THE BODY-LIQUID SAMPLING CIRCUIT BOARD

摘要

A circuit board for body fluid collection includes a belt-like supporting substrate, and a plurality of measurement units defined in the supporting substrate along the longitudinal direction of the supporting substrate. The measurement units each include a puncture needle formed from the supporting substrate along the longitudinal direction of the supporting substrate by forming an opening in the supporting substrate, an insulating base layer formed on the supporting substrate, and a conductive layer formed on the insulating base layer and including an electrode for making contact with a body fluid collected by puncturing with the puncture needle.
