PROBLEM TO BE SOLVED: To provide an antistatic tool capable of excellently and surely diffusing, to an outside, an electric charge charged on a flow passage through which fluid can flow, and preventing the flow passage from coming off and also preventing fluid leakage.SOLUTION: An antistatic tool 5 is attached to the flow passage, trough which the fluid can flow, in such a manner that a predetermined portion of the antistatic tool is contactable with the fluid, and capable of diffusing the electric charge charged on the flow passage to the outside by coming in contact with grounding means E, which performs electrical grounding. The antistatic tool has a conductive member 6 that comprises a fluid contact part 6b inserted in an insertion hole L2a, which is formed in the flow passage so as to be contactable with the fluid, and a ground part 6c capable of diffusing the electric charge charged on the flow passage to the outside by coming in contact with the grounding means E so as to be groundable, the fluid contact part 6b and the ground part 6c being integrally formed.SELECTED DRAWING: Figure 7【課題】液体が流通し得る流路に帯びた電荷を良好且つ確実に外部に放散し得るとともに、流路が外れてしまうのを回避しつつ液漏れを抑制することができる帯電防止具を提供する。【解決手段】液体が流通し得る流路に取り付けられ、所定部位が液体に接液可能とされるとともに、電気的に接地させる接地手段Ｅと接触することにより流路に帯びた電荷を外部に放散可能な帯電防止具５において、流路に形成された挿通孔Ｌ２ａに挿通されて液体に接液可能な接液部６ｂと、接地手段Ｅと接触して接地可能とされ、流路に帯びた電荷を外部に放散させ得る接地部６ｃとが一体形成された導電性部材６を有するものである。【選択図】図７
