Abstract: The present invention relates to a method of manufacturing a separator with excellent uniformity of material properties by preventing the separator from being dried before being injected to a dryer as water is supplied to the separator before the separator is injected to the drier after a diluent is extracted from the separator during the manufacturing of the separator. More specifically, the present invention relates to a method of manufacturing a porous polyolefin-group separator which includes: formation of a sheet including a polyolefin-group resin and a diluent; extraction of the diluent from the sheet; and drying the sheet after the extraction to manufacture a separator. After the extraction of the diluent and before drying, water is supplied to the separator. Also, the present invention relates to a separator manufactured by the method described above and an electrochemical battery using the same.
