Electrolytic capacitor and method for producing the same.

摘要

An electrolyte of an electrolytic capacitor (1-4) comprises at least one ammonium salt and at least one polyether polyol having a skeletal structure represented by the formula: <CHEM> where, each of Rs independently represents a hydrogen atom, an optionally substituted isocyanate residue or acrylic residue which may be the same as or different from one another; m<5>, m<6>, m<7>, n<5>, n<6> and n<7> each represent a positive integer, and the ends of the isocyanate residues or the acrylic residues are 3-dimensionally linked. <IMAGE>
