PROBLEM TO BE SOLVED: To provide a method of manufacturing a biosensor integrated with a puncture device facilitating the manufacture by forming the biosensor in an extremely simple structure while retaining sufficient strength withstanding an impact by puncture performed by a user himself/herself, and capable of reliably measuring a small amount of sample solution by minimizing the biosensor as a whole.SOLUTION: The biosensor integrated with the puncture device uses a puncture needle formed with at least two electrodes on the inner wall of the hollow needle with a hole section. The biosensor is manufactured by inserting a tubular electrode, which is formed of conductive materials constituting the electrodes and an electric insulation material into stripe shape by an extrusion molding method, into the hollow needle.COPYRIGHT: (C)2010,JPO&INPIT【課題】使用者自らが行なう穿刺による衝撃にも充分に耐えうる強度を保持しつつ、極めて単純な構造により形成することで、作製が容易であり、また全体として微小化することで少量の試料液でも確実に測定を行うことを可能とする穿刺器具一体型バイオセンサーの製造法を提供する。【解決手段】中空針に、電極をなす導電性材料と電気絶縁性材料を押出し成形法によりストライプ状に形成したチューブ状の電極を挿入することにより、孔部を有する中空針の内壁に少なくとも2電極を形成せしめた穿刺針が用いられた穿刺器具一体型バイオセンサーを製造する。【選択図】図1
