PROBLEM TO BE SOLVED: To provide a bellows pump improved so as to prevent a disadvantageous phenomenon of a hole being opened in a bellows due to discharge caused by electrification of static electricity by preventing electrification in a pump interior. SOLUTION: The bellows pump has a pump body 1 including a suction passage 12 and a discharge passage 13 of a chemical, a bellows 2 disposed in a state of forming a sealed space 11 with the pump body 1 with one end air-tightly fixed to the pump body 1, an operation part 15 provided in another side of the bellows 2 to extend and contract the bellows 2 with respect to the pump body 1, a suction valve 6 provided in the suction passage 12 communicated with the sealed space 11, and a discharge valve 7 provided in the discharge passage 13 communicated with the sealed space 11. It includes a current collecting member C made of a conductive material facing the sealed space 11, and a conductive means D with one end conductively connected to the current collecting member C and having another end facing an exterior of the pump body 1.
