摘要：
An optical disc manufacturing method includes: an injection step of injecting a liquid material into a circular plate-shaped injection space having a center hole portion at a center from an injection hole connected to an inner edge portion in the injection space; a discharge step of discharging air and the liquid material from a discharge hole formed on a straight line passing through the injection hole and a center of the center hole portion in a plane direction of the circular plate and at a position opposite to the injection hole; a curing step of curing the liquid material injected into the injection space; and a takeout step of taking out the cured liquid material from the injection space.
