Adhesive layer coating unit, electrode assembly manufacturing apparatus comprising same, and electrode assembly manufacturing method

An adhesive layer coating unit configured to continuously apply an adhesive layer having a first width in a longitudinal direction of a first separator, the adhesive layer coating unit comprising:

• a transfer roller configured to support a bottom surface of the first separator and to move the first separator;
• a discharge roller configured to move the first separator in conjunction with the transfer roller while supporting a top surface of the first separator, the discharge roller defining a coating groove having the first width in a direction parallel to a rotational axis of the discharge roller and a closed curve shape extending below an outer circumferential surface of the discharge roller, the first width being 3-7% of a width of the first separator;
• and
• a coating member configured to inject an adhesive into the coating groove between the discharge roller and the top surface of the first separator, the coating member being configured to continuously apply a continuous line of the adhesive layer having the first width onto the top surface of the first separator.
