Summary:To fix an insulating material at a periphery of a terminal on an exterior material with a strong force.SOLUTION: A battery cell 100 includes a battery element 110, an exterior material 120 that seals the battery element 110, a negative electrode terminal 134 electrically connected to the battery element 110 and drawn out of the exterior material 120, and a first insulating tape 140 that surrounds the periphery of the negative electrode terminal 134 of the exterior material 120. The first insulating tape 140 is bonded together at least partially.SELECTED DRAWING: Figure 4 【課題】外装材における端子の周囲に絶縁材を強い力で固定する。【解決手段】電池セル１００は、電池要素１１０と、電池要素１１０を封止する外装材１２０と、電池要素１１０に電気的に接続され外装材１２０から引き出された負極端子１３４と、外装材１２０の負極端子１３４の周囲を覆う第１絶縁テープ１４０と、を備えている。第１絶縁テープ１４０は、少なくとも部分的に互いに接合されている。【選択図】図４
