To improve a yield in a manufacturing method of an image display device by reducing remaining gas pressure in a vacuum container, by improving the service life of the device, by reducing the damage at the time of exhaust pipe connection, by performing the connection independently of the shape of the end face of the exhaust pipe and by simply repairing a defect at the time of the connection.

This manufacturing method is used to manufacture an image display device having at least an envelope 101 that can be brought into a vacuum-tight state and an exhaust pipe 103 for evacuating the inside of the envelope 101. In this case, the image display device manufacturing method has a process wherein the exhaust pipe 103 is inserted into an exhaust pipe connection part 105 of an exhaust means 106 provided with the exhaust pipe connection part 105 having an inside diameter larger than the outside diameter of the exhaust pipe 103 of the envelope of the image display device, the exhaust pipe 103 is sealed and connected with the outside peripheral part of the exhaust pipe connection part 105, and the exhaust is then performed.
