A puncture tool (100) with a mechanism for relieving needle puncture pain includes a puncture tool (1), and needle-puncture-pain relieving means (11) for relieving pain when the surface of a fingertip pulp is punctured by the puncture needle (23) of a puncture needle cartridge (2). The needle-puncture-pain relieving means (11) has a body portion (12). The body portion (12) has a base portion (123), a puncture portion (124) facing a fingertip pulp, a clip portion (120) having a pair of clip pieces (121, 121) arranged to face each other through the puncture portion (124) and abutting against the opposite sides of a fingertip, respectively, and a pair of elastically deforming portions (122, 122) for coupling the base portion (123) with the clip pieces (121). A pair of piezoelectric elements (13, 13) are provided in the pair of clip pieces (121, 121), and vibratory stimulation is imparted to the opposite sides of a fingertip as the respective piezoelectric elements (13) vibrate.
