In an optical-disk manufacturing device in which a disklike plate is coated with an ultraviolet-set resin on one side thereof, pressed against a stamper, and irradiated by ultraviolet rays to transfer a pattern provided in the stamper to the ultraviolet-set resin, the optical-disk manufacturing device has a disklike-plate supplying section which can store a plurality of disklike plates; a resin supplying section for supplying the resin to the disklike plate; a transfer section for transferring the pattern of the stamper to the resin; a disklike-plate removing section for removing the disklike plate after transferring; and a transport device to transport the disklike plate from each proceding part to each following part. The various sections of the device are arranged in alignment with a central line passing through a first position of the transfer section, where the disklike plate is overlaid upon the stamper, and at least a second postion of the transfer section, where the resin sandwiched between the disklike plate and the stamper is irradiated by the ultraviolet rays is substantially vertical to the alignment of the sections of the manufacturing device.
