Zusammenfassung:	Provided is a hot stamping part. The hot stamping part of the present invention comprises: a base material; a decarburization layer disposed on a surface of the base material; and an internal oxide layer disposed on a surface of the decarburization layer. The hot stamping part has a tensile strength (TS) of 1680 MPa to 2000 MPa, and the hardness within a depth of 50 μm in the plate thickness direction of the hot stamping part from the surface of the hot stamping part and the average hardness of the hot stamping part satisfy the following relational expression 1. (A / B)
