A polyurea electrolyte includes a polyurea resin formed by a polymerization of a first compound having two or more isocyanate groups and a second compound having two or more amino groups. The first compound or the second compound contains ten or more carbon chains, and the first compound or the second compound contains a sulfonic acid group or a carboxylic acid group. A method for manufacturing the polyurea electrolyte includes neutralizing the sulfonic acid group or the carboxylic acid group in the first compound or the second compound by a neutralizing agent; after the neutralizing, polymerizing the first compound and the second compound; and after the polymerizing, removing the neutralizing agent from a polymer of the first compound and the second compound.
