PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing device for an image display capable of efficiently manufacturing a vacuum envelope such as SED with no failure such as the breakage or coming-off of an reinforcing member (spacer) that supports a vacuum pressure load applied between a front board and a rear board of the vacuum envelope. SOLUTION: In a baking process (heating process) in a baking/electron beam cleaning chamber 102, baking is performed by separating a front board 2 away from a rear board 4 up to a distance at which gas generated at the central part of the front board 2 and the rear board 4 which are heated by a heating means 42 does not stay for smooth degassing. In a cooling process in a cooling chamber 103 thereafter, the front board 2 is made to approach the rear board 4 up to a distance at which a spacer 8 supported by the rear board 4 sufficiently receives heat radiated from the front board 2 and the temperature of the spacer 8 approaches the temperature of the rear board 4, for performing a cooling process by a cooling means 43.
