An object of the present invention is to provide a very simple structure while maintaining sufficient strength to withstand impact caused by puncture performed by the user himself / herself. Provided is a biosensor integrated with a puncture device that enables reliable measurement even with a liquid. A puncture device-integrated biosensor using a puncture needle in which at least two electrodes are formed on the inner wall of a hollow needle having a hole. This biosensor integrated with a puncture device has a very simple structure because a needle and an electrode are integrally formed for collecting a sample body fluid, and thus is easy to manufacture, and also has capillary action or vacuum blood collection. By providing a blood collection means according to any one of the methods, the sample body fluid can be reliably collected in a small amount without waste. [Selection] Figure 1 |
