71 ~ Cellulose fibers such as paper are widely used, and in electrolytic capacitors using conventional separators, chemical reactions between the electrolyte and the separator occur when the capacitor is used for a long period of time, making it difficult to maintain stable characteristics sufficiently. There were some drawbacks that made it unsustainable. In other words, in an electrolytic capacitor using a conventional separator, for example, electrolytic capacitor characteristics such as capacitance (Cap, ), dielectric loss tangent (tan δ), and impedance (l1np, ) when used for a long period of time under harsh conditions A significant decrease in properties was observed, and it has been desired to avoid or alleviate this decrease in properties.

れる。One possible reason for not being able to maintain stable properties is that some kind of inconvenient chemical reaction occurs when the properties deteriorate, resulting in deterioration of the separator. An example of this is an esterification reaction between the hydroxyl groups of the fibers and carbonic acid, which is a component of the electrolyte of the electrolyte type capacitor. It is believed that this esterification reaction leads to the consumption of ions that are effective in maintaining the properties, and particularly deteriorates the capacitor properties.

されたものである。However, such conventional electrolytic capacitors using separators have drawbacks such as chemical reactions between the electrolyte and the separator when the capacitors are used for a long period of time, making it impossible to maintain sufficiently stable characteristics. The present invention was completed as a result of studies conducted from the viewpoint of suppressing the chemical reactivity of such conventional separators as to whether the contribution of hydroxyl groups in cellulose fibers is considered to be the cause of this chemical reaction.

Paper made by mixing PPS or aramid fibers with glass fibers is heat treated (heating and pressure treatment) to fuse the fibers (
Alternatively, the strength of the nonwoven fabric can be improved by contacting it.
