BATTERY PACK

To provide a technique which can prevent, with a simple configuration, short-circuiting in a connection portion between a first electrode tab and a second electrode tab.SOLUTION: A battery pack may comprise: a first unit cell having a first electrode tab; and a second unit cell having a second electrode tab. The first electrode tab and the second electrode tab are juxtaposed, and both tabs may be connected to each other via a connection member. The battery pack may comprise first insulation tape extending in a direction where the first electrode tab and the second electrode tab are juxtaposed. The first insulation tape may be adhered to the first electrode tab, the second electrode tab, and the connection member in such a manner that it covers surfaces on one side of the first electrode tab, the second electrode tab, and the connection member.SELECTED DRAWING: Figure 2 【課題】第１電極タブと第２電極タブの接続部分でショートが生じることを簡潔な構成で抑制することができる技術を提供する。【解決手段】組電池は、第１電極タブを備えている第１単電池と、第２電極タブを備えている第２単電池と、を備えていてもよい。前記第１電極タブと前記第２電極タブが隣り合うように配置されており、両者が接続部材によって接続されていてもよい。組電池は、前記第１電極タブと前記第２電極タブが隣り合う方向に延びている第１絶縁テープを備えていてもよい。前記第１絶縁テープは、前記第１電極タブと前記第２電極タブと前記接続部材の一方側の面を覆うように前記第１電極タブと前記第２電極タブと前記接続部材に貼り付けられていてもよい。【選択図】図２
