A manufacturing method of an impeller includes forming a plurality of blades integrally on a blade attachment surface of one of a disc and a cover, placing the cover on a floor so as to face up the blade attachment surface of the cover, disposing the disc on the cover so as to face down the blade attachment surface of the disc, and bonding the plurality of blades to the blade attachment surface of the other of the disc and the cover which is not formed integrally with the plurality of blades by using a bonding material.

There is provided a hydrogen separation membrane capable of providing high hydrogen permeability and accommodating an increase in pressure difference, a hydrogen separation unit, and a manufacturing method for a hydrogen separation membrane. The hydrogen separation unithas a hydrogen separation membraneand a metallic porous support sheetattached to the hydrogen separation membrane. By forming a plurality of pits in the surface of the hydrogen separation membrane, a thick-wall portionhaving a large thickness and a thin-wall portionhaving a small thickness are provided on the hydrogen separation membrane. Also, as a method for forming pits i.e. thin-wall portions, etching process is used.

A twin drum type continuous casting apparatus is provided for continuously feeding molten metal into a cast portion defined by a pair of water cooling drums that are rotated in opposite directions to each other, thereby continuously casting a plate-like cast piece. A thin portion is formed close to an outer circumferential portion of each of opposite end portions, in a width direction, of each of the water cooling drums. A thin annular member having a hot water flow passage therein is formed in between the thin portion and a shaft with a space relative to an end face of each of the water cooling drums.
