PROBLEM TO BE SOLVED: To provide a lithium battery cell capable of sufficient degassing since spaces exist around gas exhaust holes formed at a terminal part because only the upper gas exhaust holes are formed at the terminal part of the cylindrical lithium battery cell, and furthermore, capable of enhancing gas exhaust efficiency since an electrolytic solution is prevented from leakage, and gases exhausted from the gas exhaust holes are prevented from overlapping because only the upper part gas exhaust holes are formed in a structure of a lithium battery formed by transversely arranging a plurality of cylindrical lithium battery cells in a lithium battery pack. SOLUTION: In the structure of the lithium battery, the plurality of the cylindrical lithium battery cells are transversely arranged in the lithium battery pack, and only the upper part gas exhaust holes 213 are formed at the terminal part 21 of the cylindrical lithium battery cell 2.
