A disc molding die, which can uniformly cool a molding object and does not generate printing nonuniformity in a printing area of the molding object, and a molded object are provided. The disc molding die is provided with a first die plate, a first mirror-surface plate, a second die plate arranged to freely advance and retreat to and from the first die plate, a second mirror-surface plate for forming a cavity with the first mirror-surface plate in a clamping state, a stamper (32), which is attached to one of the first and the second mirror-surface plates and has a fine pattern formed on its front edge plane, and a bush (55) arranged by penetrating the other of the first and the second mirror-surface plates. On a front edge plane of the above mentioned the other mirror-surface plate, the bush (55) is arranged inner than an area for forming a clamp area in a diameter direction. In this case, since an area of a front edge plane of the bush (55) becomes small, molding object cooling performance is prevented from deteriorating. |
