The invention provides a waste gas treating apparatus for effectively executing heat treatment for waste gas containing warm gas. The waste gas is introduced from a waste gas introducing section (12) into a heating treatment section (14). The waste gas is pyrolyzed mainly by radiation heat heated with an electromagnetic induction heating unit (22) and coming from a circular cylinder tube (20), in process of one-way pass from its base end section to end section in a circular cylinder tube of the heating treatment section.
