Abstract: A pressure adjustor includes a sheet-like supporter formed of unwoven fabric or woven fabric, a plurality of activated carbon powder particles attached to the supporter, and binders binding the plurality of activated carbon powder particles to each other. If this pressure adjustor is disposed inside a cabinet of a speaker device including a speaker unit provided in the cabinet, a speaker device is obtained which has an excellent bass reproduction effect even if the device is made small.

Abstract: A capacitor includes a film previously provided on both sides or one side of a collector by anodizing or the like, further a conductive layer provided on the film, and a polarizable electrode layer as an electrode portion on the conductive layer. Thus, the capacitor suppresses the reaction between a driving electrolyte and the collector after a long time of use because the reactivity between the film previously provided on both sides or one side of the collector and the driving electrolyte is low. Furthermore, since the conductive layer is provided, it is possible to reduce an initial contact resistance on the surface of the collector, and to enhance an effect of suppressing performance deterioration by the film.

Abstract: A polarizable electrode includes a collector and a polarizable electrode layer having a thickness of 5 ?m or more to 130 ?m or less on the surface of the collector. The polarizable electrode layer includes a first binder composed of at least one of an ammonium salt of carboxymethyl cellulose, polyvinylpyrrolidone, polyvinyl alcohol, methylcellulose, and a hydroxylpropyl cellulose resin, and a second binder composed of at least one of a latex, a fluoride-based polymer, a urethane resin, and an olefin-based resin. The content of the first binder is 5% by weight or less with respect to the total weight of the solid part, and the content of the second binder is 1% by weight or more and 5% by weight or less.
