High-frequency induction heating device

A high-frequency induction heating device comprising:

• an introduction part which introduces a gas to be treated,
• a pyrolysis part which pyrolyzes the gas to be treated,
• an induction heating coil provided around the outer circumference of said pyrolysis part so as to surround and heat said pyrolysis part, and
• an exhaust part which exhausts the gas having been decomposed in said pyrolysis part;
• said pyrolysis part comprising a cylindrical body which introduces the gas provided so that the cross-section of the passage of said cylindrical body becomes smaller from the upstream towards the downstream.
