A biosensor cartridge capable of performing puncturing in an exact position, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When tip portion 11a of biosensor chip body 11 is pushed against a subject M, elastic body 20 protruding from a tip portion 11a of biosensor chip body 11 is compressed, and puncturing tool 12 for puncturing protrudes. Thus, the subject M can be punctured. Additionally, if a pushing force is weakened, puncturing tool 12 is extracted from the subject M by the restoring force of elastic body 20, and the sample R flows out of the puncture hole. Additionally, cover member 19 is provided around biosensor chip body 11. Thus, when puncturing is performed by thin plate-shaped biosensor cartridge 10, biosensor chip body 11 can be prevented from deforming, and puncturing can be accurately performed in a desired puncturing position. |
