Zusammenfassung:	PROBLEM TO BE SOLVED: To improve longevity of an insulation member of a plasma torch wherein an electric insulation member is arranged between a nozzle and a cap. SOLUTION: An insulation member 11 is arranged between a nozzle 7, which generates a plasma arc by discharging electricity between an electrode, and a cap 12 being screwed in an outer cylinder. On the insulation member 11, a ceramic part 11a is arranged at a portion exposed to the air, and a synthetic resin part 11b is at a portion facing to an inside spacing 14. The synthetic resin part 11b is formed in a way to have a boss part 11c and a flange part 11d, wherein it contacts with an O ring 15 being mounted on a protruded part 7a formed at a tip end of the nozzle 7.
