PROBLEM TO BE SOLVED: To provide a gas mixing apparatus which incorporates a gas supply means to shorten the length of the apparatus in the gas flowing direction by devising the composition of the gas mixing apparatus. SOLUTION: A plurality of mixing elements 2A formed by inserting and fixing fins 23 on a circular passage 22 are arranged in parallel to each other and annularly to form a static mixer. A blower 3 supplying air as second gas to the static mixer 2 is almost entirely accommodated and fixed in the inner peripheral space of the static mixer 2. Thereby, the blower 3 as the gas supply means which is arranged in series with the gas mixing apparatus in the conventional gas mixing apparatus is arranged in parallel with the static mixer 2 and the overall length L of the gas mixing apparatus 1 can be shortened.
