Zusammenfassung:A diaphragm includes a paper layer and a skin layer. The paper layer includes natural fibers and synthetic fibers formed of thermoplastic resin. The paper layer is formed by mixing the natural fibers and the synthetic fibers in water, and thinly spreading a resultant mixture on a mesh. The skin layer is formed on one surface of the paper layer. Note here that the skin layer is formed of the same resin as that of the synthetic fibers.
