Electrolytic capacitor and method for producing the same

摘要

An electrolyte of electrolytic capacitor comprises at least one ammonium salt and at least one polyether polyol having a skeletal structure represented by the formula: <IMAGE> 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; m1, m2, m3, n1, n2 and n3 each represent a positive integer, and the ends of the isocyanate residues or the acrylic residues are 3-dimensionally linked.
