Summary:[Problem] An object of the present invention is to improve the operativity of a front end side of a plasma guide wire.[Solution] Provided is a plasma guide wire comprising a core shaft, a coil, a tip, a coil-core shaft joining region, and the first to third insulating resin tubes. The first insulating resin tube is disposed on the outer periphery of the coil, and extends from the tip to the rearward of the coil-core shaft joining region. The second insulating resin tube is disposed on the outer periphery of the core shaft, and joined to the rear end of the first insulating resin tube, and extends from the rear end of the first insulating resin tube to the rearward of the core shaft. The second insulating resin tube is harder than the first insulating resin tube. The third insulating resin tube is disposed on at least a portion of a region of the inner periphery of the first insulating resin tube, the region being located rearwardly relative to a location facing the rear end of the coil.
