The invention discloses an induction plasma torch and a tubular torch body. The induction plasma torch comprises a tubular torch body with an inner surface; a plasma confinement tube disposed in the tubular torch body coaxial therewith; a gas distributor head disposed at one end of the plasma confinement tube and structured to supply at least one gaseous substance into the plasma confinement tube; an inductive coupling member embedded into the tubular torch body and used for applying energy to the gaseous substance to produce and sustain plasma in the plasma confinement tube; and a capacitive shield positioned on the inner surface of the tubular torch body, wherein the capacitive shield is segmented into axial strips interconnected at one end. 本发明公开了感应等离子体焰炬和管状焰炬体。感应等离子体焰炬包括：管状焰炬体，具有内表面；等离子体限制管，布置在所述管状焰炬体中，与所述管状焰炬体同轴；气体分配器头，布置在所述等离子体限制管的端，并构造成将至少种气体物质供应进所述等离子体限制管中；感应耦合构件，嵌入所述管状焰炬体内，用于对气体物质施加能量，以在所述等离子体限制管中产生并维持等离子体；以及导电的电容屏蔽层，位于所述管状焰炬体的内表面上，其中，所述电容屏蔽层被分割为轴向条，并且这些轴向条在端互相连接。
