To lower manufacturing cost, and easily hold and fix a conductive tube while securing sufficient discharge performance in a simple constitution in a conductive tube holder.

This conductive tube holder 1 comprises a clamp type tube holding part 2 to hold side surfaces of each conductive tube 9 by a pair of semi-tubular parts 4a and 4b in surface-contact with them, and a grounding installation part 3 to get in surface-contact with a grounding body 10 on the external to be locked by bolts 11. The tube holding part 2 and the grounding installation part 3 are integrally formed of conductive resin to discharge static generated at the conductive tube 9 to the grounding body 10. The conductive tube holder 1 is in a simple constitution, and it can be manufactured at low manufacturing cost. A trunk part of the conductive tube 9 can be securely held and fixed while securing sufficient discharge performance by easy work.
