Abstract
Adhering apparatus for plate shaped matter includes absorbing-and-holding means serving also as electrodes for absorbing and holding respectively first optical disc substrate and second optical disc substrate , optical disc substrate moving means for moving second optical disc substrate to be approached to first optical disc substrate, distance detecting means for detecting the distance between optical disc substrates, velocity controlling means for controlling a relative velocity of the second plate shaped matter to the first plate shaped matter and controlling the plate shaped matter moving means in such a manner that the relative velocity immediately after and at a time point at which the adhesive applied onto the first plate shaped matter is brought in contact with the second plate shaped matter is slower than that immediately before the adhesive applied onto the first plate shaped matter is brought in contact with the second plate shaped matter; and voltage application means for applying voltage between the first plate shaped matter and the second plate shaped matter before the adhesive applied onto the first plate shaped matter is brought in contact with the second plate shaped matter.
