Summary:PURPOSE: A plasma torch and an apparatus for producing nano powder including the same are provided to uniformly change a source gas into nano powder by preventing the source gas from being suddenly cooled. CONSTITUTION: A plasma torch(300) comprises a cylindrical induction coil structure(310), a plasma generating tube(320), and an injection tube(340). An induction coil is rolled around the induction coil structure. The induction coil is applied with high frequency power for producing plasma from the outside. The plasma generating tube is arranged to be coaxial to the induction coil structure in the inner side of the induction coil structure to produce the plasma. The injection tube supplies a raw material to the inside of the plasma generating tube in the top part of the plasma generating tube. An interval between induction coils becomes narrower from the both end parts of the induction coil to a central part.
