Claim 0:
1. A secondary battery comprising:
an electrode assembly comprising a first electrode plate, a second electrode plate, and a separator between the first electrode plate and the second electrode plate;
a case configured to accommodate the electrode assembly; and
an adhesive part on an outermost region of the electrode assembly,
wherein, in a longitudinal direction of the electrode assembly, the separator extends longer than at least one of the first electrode plate or the second electrode plate so as to extend beyond a boundary line between the separator and an end of the at least one of the first electrode plate or the second electrode in the longitudinal direction,
wherein the adhesive part is adjacent to an end of the separator beyond the boundary line, and is bonded to the case in a state in which the electrode assembly is accommodated in the case, and
wherein the electrode assembly further comprises a tape which is attached to an end on the adhesive part adjacent to the boundary line between the negative electrode plate and the separator or between the positive electrode plate and the separator.
