A continuous firing furnace of the present invention comprises: a muffle formed into a cylindrical shape so as to ensure a predetermined space; a plurality of heat generators placed at the peripheral direction from the muffle; and a heat insulating layer formed in a manner so as to enclose said muffle and said heat generators therein, said continuous firing furnace being configured such that a formed body to be fired, which is transported from an inlet side, passes through the inside of said muffle at a predetermined speed in an inert gas atmosphere and, then, is discharged from an outlet so that said formed body is fired, wherein said inert gas flows through: a space between said muffle and said heat insulating layer; and a space inside the muffle, in sequence.
