Method for producing image-forming apparatus, and image-forming apparatus produced using the production method

An airtight vessel is formed with restraining a vacuum leak and without increase in the number of steps. Provided is a method for producing an image-forming apparatus comprising the airtight vessel in which a rear plate having an electron-emitting device and a wire connected to the element, and a face plate having an electrode are joined to each other through a jointing material, the method comprising the following steps: (A) a first step of forming a first wire which is a part of the wire and which passes through the joint part to connect the inside of the vessel to the outside, by applying a paste comprising particles of an electric conductor and baking the paste; and (B) a second step of forming a second wire located in the vessel, by applying a paste comprising particles of an electric conductor so as to be connected to the first wire inside the vessel and baking the paste, after formation of the first wire.
