Provided is a puncture tool having no possibility of starting the puncture operation of a puncture needle unexpectedly when the puncture tool is operated for a purpose other than measurement of a biological sample and also provided are a device for measuring biological sample and a system for measuring biological sample. A puncture tool (100) comprises a puncture mechanism (110), a puncture mechanism control section (120) which controls puncture operation of the puncture mechanism (110), a wireless communication section (140) which performs wireless authentication by receiving a wireless signal from an external registration apparatus (200), and a puncture control circuit (150) which removes restriction on puncture prohibition of the puncture mechanism control section (120) when authentication is established at the wireless communication section (140). The puncture tool (100) can perform operation for urging puncture only when a puncture permission signal is issued from an external registration apparatus (200) which is registered externally.
