Abstract:
1. An anodic bonding apparatus for bonding a laminated substrate, comprising: a first electrode having a first surface, said first surface including a first central area; a first substrate placing area for placing the laminated substrate and containing the first central area; and a first peripheral area surrounding the first substrate placing area; and a second electrode having a second surface facing the first surface, said second surface including a second central area corresponding to the first central area; a second substrate placing area corresponding to the first substrate placing area and surrounding the second central area; and a second peripheral area corresponding to the first peripheral area and surrounding the second substrate placing area, said second electrode further including a curved portion curved toward the first electrode so that a distance between the first central area and the second central area becomes smaller than a distance between the first peripheral area and the second peripheral area, said second electrode being formed of a material containing carbon as a main component.
