An electronic device package manufacturing method includes: forming a metal film on both surfaces of the cover substrate so that the metal film on one surface and the metal surface on the other surface conduct with each other; aligning and superimposing the cover substrate and the base substrate; and bonding the base substrate and the cover substrate together via the metal film by anodic bonding by bringing a negative electrode plate into contact with the base substrate on an entire surface opposite to a surface bonded to the cover substrate, bringing a positive electrode plate into contact with the cover substrate on an entire surface opposite to a surface bonded to the base substrate, and applying a voltage between the positive and negative electrode plates. The base substrate and the cover substrates can be thus bonded together via the metal film by anodic bonding in a stable manner.
