PROBLEM TO BE SOLVED: To provide a continuous baking furnace capable of preventing diffusion of a reaction formation gas to an outlet side of a furnace body while suppressing a flow rate of an atmospheric gas. SOLUTION: This continuous baking furnace comprises a roller conveyor 3 for conveying a baked object W, an introduction pipe on a carrying-out port side for introducing the reaction gas G into a furnace body, an exhaust pipe on a carrying-in port side for exhausting the gas in the furnace body to the outside of the furnace body, a reaction gas supply pipe 9 having a plurality of blowout holes 9a for blowing out the reaction gas in the longitudinal direction in an area where the reaction formation gas G1 is generated by the reaction of the baked object and the reaction gas, and a reaction gas recovering pipe 10 having a plurality of suction holes 10a for sucking the gases G, G1 in the longitudinal direction, and the reaction gas supply pipe and the reaction gas recovering pipe are arranged so that the blowout holes and the suction holes are opposite to each other at a height position of a top face of the baked object or a position higher than the same.
