しい。The addition amount of the inorganic substance is preferably 5.0 to 60% by weight, because if it is 5% by weight or more, the ability to retain the electrolyte is low, and if it is 60% by weight or more, the inorganic substance retention is poor. Further, if the binder is less than 1% by weight, it has no ability, and if it is more than 5% by weight, the amount of liquid retained is reduced due to water repellency, so the binder is preferably 1 to 6% by weight.
