A disclosed disk substrate conveying mechanism includes a plurality of screw shafts each including a guiding groove provided in a helical manner, which guiding grooves are configured to support an outer peripheral edge of a disk substrate molded with a die. The screw shafts are axially rotated to convey the disk substrate in a conveying direction. Each of the guiding grooves includes a front side wall at the front of the guiding groove in the conveying direction, a back side wall at the back of the guiding groove in the conveying direction, and a base face that is tilted in such a manner that the guiding groove becomes deeper gradually from the back toward the front in the conveying direction.
