Claim 14:
15. A method of producing a high-temperature component which requires cooling by a cooling medium, wherein the high-temperature component comprises:
a plurality of cooling passages through which the cooling medium is able to flow; and
a first partition wall disposed inside each of the cooling passages to partition each cooling passage into a plurality of first branch flow passages,
wherein each cooling passage includes, in an extending direction of the cooling passage, a first section in which the first partition wall is provided and a second section in which the first partition wall is not provided, the second section being upstream of the first branch flow passages, and
wherein for each cooling passage, the first partition wall includes an oblique portion formed such that, in an upstream side region of the first partition wall, a flow-passage cross-sectional area of the cooling passage as seen in the extending direction of the cooling passage gradually decreases from an upstream side toward a downstream side,
the method comprising:
forming, by metal additive fabrication, the plurality of cooling passages through which the cooling medium is able to flow inside the high-temperature component, and forming the first partition wall disposed inside each of the cooling passages to partition each cooling passage into the plurality of first branch flow passages.
