Abstract
PURPOSE:To make tension of a vibration film fixed and improve a work efficiency by eliminating the whole or a part of the second film by etching after causing a film, where the second film which can be etched is laminated on one face of the first film which becomes the vibrating film, to one face of a ring. CONSTITUTION:Film 10 and 11 are laminated to form lamination film 12. This film 12 is cause to adhere onto the lower face of ring 2 by heat fusion or adhesive, etc. Film 11 consisting of polyimide is eliminated by etching after adhesion of film 12, and film 10 consisting of a copolymer (FEP) of ethylene tetrafluoride and propylene hexafluoride is left, and this film 10 becones a vibrating film. Since polyimide film 11 is laminated on one face of FEP film 10 which becomes the vibrating film to reinforce FEP film 10 and FEP film 10 is caused to adhere to a ring in this manner, irregularity of tension of the vibrating film is not generated, and the work efficiency in the adhesion process to the ring is improved.
