Pouch-type secondary battery and method of manufacturing the same

A pouch-type secondary battery, comprising:

• a battery case;
• and
• an electrode assembly received in the battery case,
• wherein the battery case is composed of an upper case and a lower case made of a laminate sheet comprising an outer coating layer, a metal layer, and an inner coating layer,
• wherein the battery case includes a sealing portion at which the upper case and the lower case are coupled to each other at an outer periphery of the upper case and the lower case, and
• wherein a conformal coating layer configured to prevent exposure of the metal layer is formed at a side surface of the sealing portion,
• wherein
• a resin coating layer is further formed on a predetermined area of an outer surface of the conformal coating layer, the resin coating layer being formed by melting a portion of the outer coating layer,
• wherein the predetermined area of an outer surface of the conformal coating layer is disposed between a terminal end of the metal layer and the resin coating layer in a width direction of the pouch-type secondary battery, the terminal end extending perpendicular to the width direction.
