Abstract: A member for semiconductor manufacturing apparatus includes: a ceramic plate that has an upper surface including a wafer placement surface; a conductive base that is disposed on a lower surface of the ceramic plate; a first hole that extends through the ceramic plate; a second hole that extends through the conductive base; a porous plug that has an upper surface that is exposed from an upper opening of the first hole and a lower surface that is flush with or below an upper surface of the conductive base; an insulating pipe that has an upper surface that is located below the wafer placement surface and a lower surface that is located below the lower surface of the porous plug; and an integrally formed member that is obtained by integrally forming the porous plug and the insulating pipe.
