Abstract
In a manufacturing method of a turbine housing having an exhaust gas flow path, the exhaust gas flow path in the turbine housing is formed of a sheet-metal-made divided body and a cast-metal-made divided body, the sheet-metal-made divided body is formed by press molding a sheet metal material, and the cast-metal-made divided body is molded by casting, when the cast-metal-made divided body is cast, one end of the sheet-metal-made divided body is cast into the cast-metal-made divided body by melting the one end of the sheet-metal-made divided body such that the original shape thereof is disappeared.
