ABSTRACT:
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: ##STR1## 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.sub.1, m.sub.2, m.sub.3, n.sub.1, n.sub.2 and n.sub.3 each represent a positive integer, and the ends of the isocyanate residues or the acrylic residues are 3-dimensionally linked.
