A hot stamp molded body includes: a steel sheet (30); a first plating layer (10) on a first surface (31) of the steel sheet (30); and a second plating layer (20) on a second surface (32) of the steel sheet (30). The first plating layer (10) includes: a first Al—Fe—Si alloy layer (11) on the first surface (31); and a first Al—Si alloy layer (12) on the first Al—Fe—Si alloy layer (11). The second plating layer (20) includes: a second Al—Fe—Si alloy layer (21) on the second surface (32); and a second Al—Si alloy layer (22) on the second Al—Fe—Si alloy layer (21). A coating weight of the first plating layer (10) is 31 g/m2 to 60 g/m2 and a coating weight of the second plating layer (20) is 5 g/m2 to 29 g/m2.
