A hot stamping apparatus and a hot stamping method are for collectively decorating a plurality of decoration objects using a decorative sheet. In a hot stamping apparatus, an upper chamber and a lower chamber are partitioned by a partition sheet and pressing bodies, so that decorative sheet pieces can be used instead of a decorative sheet having a large area. Then, by using the decorative sheet pieces, local thermal deformation can be prevented. A usage amount of the decorative sheet can be reduced, and three-dimensional decoration can be implemented as needed on a portion requiring decoration.
