PURPOSE: Provided is a pouch-typed secondary battery which lets a projection part formed at the bottom of a pouch case to secure infiltration space of electrolytes and uniform space in a final product so that it prevents a battery part from being twisted. CONSTITUTION: The pouch-typed secondary battery comprises the parts of: the battery part(300) which is composed of a cathode plate, an anode plate and a separator between both plates; an electrode terminal(302) which is extended from the cathode and the anode plate; the pouch case(304) which includes a space part(202) to house the battery part and the projection part(204) formed by projecting the projection part outwardly; and electrolytes which are inserted into the pouch case having the battery part.
