PROBLEM TO BE SOLVED: To provide a substrate overlaying device that is easy to manufacture and handle, and precisely overlays substrates.SOLUTION: The substrate overlaying device includes: a first substrate holding unit which holds a first substrate having a first index for positioning on an upper surface on a first substrate holding surface, and has a light transparent part at a position where at least the first index is observed from the opposite surface side of the first substrate holding surface; a second substrate holding unit which holds a second substrate having a second index for positioning on an upper surface on a second substrate holding surface; an index observation unit for optically observing at least the first index through the light transparent part with observation light from the opposite direction of the first substrate holding surface; and a position adjusting unit which adjusts relative positions of the first substrate and second substrate according to the position of the first index observed by the index observation unit. |
