Zusammenfassung:A component part for an aluminum die-casting mold has an exposed surface that is a surface exposed to a cavity part of the aluminum die-casting mold and has diamond-like carbon coating formed at least on a part of the exposed surface, wherein the diamond-like carbon coating contains hydrogen in a content rate of 10 at % or more and 30 at % or less. The diamond-like carbon coating may further contain silicon in a content rate of less than 10 at %. Preferably, the content rate of silicon in the diamond-like carbon coating is 0.5 at % or more and 7 at % or less. Thereby, a component part for an aluminum die-casting mold which has excellent seizure resistance against molten metal containing aluminum can be provided.
