Abstract: Provided are a surface modification apparatus for an alloy steel component, a surface modification method for an alloy steel component, and a method for manufacturing an alloy steel component, which can provide a deep and homogeneous hard layer for a steel component with a wide shape or a large amount of such steel components. A surface modification apparatus 100 includes a process furnace 101, and the process furnace 101 performs a surface modification process on an alloy steel component 90 including an alloy steel material to which at least one kind of nitride formation element such as chromium, molybdenum, or aluminum is added. The surface modification apparatus 100 forms a compound layer on a surface of the alloy steel component 90 by exposing the alloy steel component 90 for at least 180 minutes to an atmosphere in the process furnace 101 maintained to have an ammonia gas concentration of 80% or more and a temperature of 620° C.
