PROBLEM TO BE SOLVED: To provide a carbon fiber production apparatus which can stably perform a flameproof treatment to obtain a carbon fiber having a high quality, and can reduce the leakage of an oven gas on the periphery of the apparatus, and to provide a method for producing the carbon fiber. SOLUTION: The carbon fiber production apparatus includes: a flameproof oven 1 for circulating a hot gas to subject a precursor fiber bundle F to a flameproof treatment; a carbonization oven 12 for carbonizing the flameproof fiber subjected to the flameproof treatment in the flameproof oven 1; a heat exchanger 14 for performing heat exchange between an exhausted gas sent from the carbonization oven 12 and an outer air; and a heated outer air-supplying route 18 for supplying the heated outer air sent from the heat exchanger 14 to the flameproof oven 1. The apparatus includes an air volume detection means 27 for detecting the volume of the heated outer air flowing in the heated outer air-supplying route 18, an air volume adjustment means 28 for adjusting the volume of the heated outer air flowing in the heated outer air-supplying route 18, and a control means 21 for controlling the air volume adjustment means 28 on the basis of information from the air volume detection means 27.
