PROBLEM TO BE SOLVED: To make a hard disk device, having a base disposed with a disk and an actuator and a cover for covering this base lighter in weight, simpler in production process and lower in manufacturing cost. SOLUTION: A cover 23A of the hard disk device, having a base 22 disposed with a disk 24 rotated by a motor 25 and an actuator 26 for moving a head 29 relative to the disk 24, and the cover 23A for covering the base 22 is constituted by integrally molding a metal plate 33 and a resin part 36, with which the cover 23A is made light in weight, simpler in the production process and lower in manufacturing cost.
