Abstract
A gas supply manifold has a nozzle forming member having a plurality of gas injection nozzles, a cover member configured to be overlapped on the nozzle forming member, and a caulking-fastening portion configured to fasten the nozzle forming member and the cover member. The caulking-fastening portion is configured such that a convex portion provided for one of the nozzle forming member and the cover member penetrates a hole provided for the other member, and a tip end portion of the convex portion has an engagement portion, the engagement portion having a larger diameter or a larger width than the hole and being engaged with a peripheral edge portion of the hole. A tip end face of the convex portion has a dent portion formed by pressing the tip end face into a base portion side of the convex portion and an area around the dent portion constitutes the engagement portion. Thus, the nozzle forming member and the cover member are appropriately caulked and fastened.
