PROBLEM TO BE SOLVED: To provide a method for manufacturing a casting apparatus and a mold-surrounding member, and the mold-surrounding member with which a heat-resistance property can be improved and a manufacturing term can be shortened. SOLUTION: Since a molten metal pouring part constituted member composed of a surface layer made of an intermetallic compound as the base material and a main body part made of a metallic material as the base material is manufactured from a process, in which mixed powder of raw material elements for intermetallic compound are filled up in a master mold having a turning-over shape of the molten metal pouring constituted member, and a process for manufacturing the intermetallic compound surface layer by reacting the filled-up mixed powder in the master mold, especially, a large scaled facility is not necessary and the high melting point intermetallic compound surface layer is simply manufactured in a second unit or a minute unit and further, the main body part of the metallic material as the base material is quickly and efficiently manufactured with overlaying and a high functional mold-surrounding member can be manufactured for extremely short time.
