The purpose of the present invention is to provide a binder capable of improving battery performance. In addition, the purpose of the present invention is to provide a binder capable of achieving low resistance and high strength of an electrode using a polytetrafluoroethylene resin. A binder is composed of a mixed powder of a polytetrafluoroethylene resin and single-walled carbon nanotubes. A method for producing a binder, in which water is used as a dispersion solvent, a polytetrafluoroethylene resin dispersion liquid and a single-walled carbon nanotube dispersion liquid are uniformly mixed and dried to produce a mixed powder. 本发明的目的在于提供一种能够提高电池性能的粘结剂。另外，本发明的目的在于提供一种在使用聚四氟乙烯树脂的电极中能够实现电极的低电阻化和高强度化的粘结剂。一种粘结剂，其由聚四氟乙烯树脂和单壁碳纳米管的混合粉末构成。一种粘结剂的制造方法，其中，使用水作为分散溶剂，将聚四氟乙烯树脂分散液和单壁碳纳米管分散液均匀混合后使其干燥，制成混合粉末。
