    • A CVD apparatus is provided to prevent cleaning efficiency from being deteriorated by relatively smoothening a flow or process gas. A reaction space(31) is formed by a chamber body(30) having an upper opening. A shower head(40) distributes process gas to form an RF electrode, installed in the upper opening. An insulator(50) includes an insulation part and a skirt part. An insulation part is interposed between the wall surface of the chamber body and the shower head to mutually insulate the chamber body and the shower head. The skirt part is extended downward from the insulation layer wherein a plurality of process gas exhausting holes(55) are radially formed in the skirt part to scatter the flow of the process gas. A shadow ring(70) is guided to the insulator so as to cover the outer circumferential surface of an object(61) in a manner that avoids formation of a deposition layer on the outer circumferential surface and the lower surface of the object.
