摘要

If the diameter of a glass substrate (1) is Dmm, and the distance from the center position (C1) of a carrier (500) to the center position (C2) of a first holding through hole (520C) of the carrier (500) is rmm, the central position (C2) of the first retaining through hole (520C) of the carrier (500) is provided in a position to satisfy the following relational expression: [(D/4)<=r<=(D/2)].
