Zusammenfassung:	A gas supply member includes an annular portion in which a passage for a gas extending to have an annular shape is provided. The annular portion includes a first member having an annular shape and including a flat plate portion in which a plurality of gas supply holes through which a gas is supplied are formed, and a second member having an annular shape and forming a space, which becomes the passage for the gas, between the first member and the second member.
