Apparatus for manufacturing a carbonaceous heat source chip, capable of drying an extrusion-molded carbonaceous heat source rod to proper hardness and supplying the same to a heat insulating material-wrapping device. The apparatus includes a hollow pipe that forms a conveying path for transporting the carbonaceous heat source rod continuously extrusion-molded by an extrusion molding machine, to the heat insulating material-wrapping device. The apparatus forms an airflow running through the hollow pipe by means of an air amplifier, and transports the carbonaceous heat source rod while drying the rod by using the airflow.
