A biosensor cartridge capable of making the collected amount of a sample required for measurement into a small quantity to reduce a user's burden, 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 one end portion of biosensor chip is pushed against subject, elastic body is compressed, and puncturing tool can protrude and perform puncturing. Additionally, if a pushing force is weakened, puncturing tool is extracted from subject by the restoring force of elastic body, and blood (sample) flows out of the puncture hole. In this case, since the puncture hole, and sample collection opening provided at biosensor chip are contained in enclosed half-open space formed by elastic body, even a small amount of blood (sample) can also be easily collected. Additionally, elastic body is formed with a groove which forms a ventilation passage, so that enclosed half-open space can be opened to the atmosphere. |
