This oscillatory component for loudspeakers has a base layer, an intermediate layer and a coating layer. The base layer has a front surface and a back surface, while having a first density and being configured from paper that is composed of a plurality of fibers. The intermediate layer has a first surface, which is bonded to the front surface of the base layer, and a second surface, which is on the reverse side of the first surface, and has a second density that is higher than the first density, while containing a plurality of cellulose fibers as the main component. The coating layer is provided on the second surface of the intermediate layer, and contains an inorganic powder that is configured of a plurality of inorganic fine particles. |
