To provide a terminal-equipped battery that is easy to conduct positioning of external terminals to be attached to a flat-type battery and thus can improve the location accuracy of the external terminals, and a manufacturing method thereof.SOLUTION: A terminal-equipped battery includes an insulation case 3 to accommodate a flat-type battery 2 having an outer can 21, a seal can 22, and an electrode body 23, and an external terminal 4 and an external terminal 5 to be connected to the flat-type battery 2. The flat-type battery 2 is accommodated in the insulation case 3 through an opening 31. The insulation case 3 has an opening 32 causing the outer can 21 to be exposed and an opening 33 causing the seal can 22 to be exposed. The external terminals 4, 5 respectively have flat parts 41, 51 and tip parts 42, 52 extending from the flat parts 41, 51. The flat parts 41, 51 are respectively fitted into the openings 32, 33 so as to be restricted from the movement in the front-and-rear and right-left directions to position the tip parts 42, 52 of the external terminals 4, 5, and are fixed to the outer can 21 and the seal can 22 via the openings 32, 33.SELECTED DRAWING: Figure 3 【課題】扁平形電池に取付ける外部端子の位置決めが容易であり、外部端子の位置精度を向上することができる端子付き電池及びその製造方法を提供する。【解決手段】外装缶２１、封口缶２２及び電極体２３を有する扁平形電池２を収容する絶縁ケース３と、扁平形電池２に接続される外部端子４及び外部端子５とを備えている。扁平形電池２は、開口部３１を通じて絶縁ケース３に収容される。絶縁ケース３は、外装缶２１を露出させる開口部３２と、封口缶２２を露出させる開口部３３をと有している。外部端子４、５は、平坦部４１、５１と平坦部４１、５１から延びる先端部４２、５２とを有している。平坦部４１、５１は各々、前後左右方向への移動が規制されるように開口部３２、３３に嵌合されて外部端子４、５の先端部４２、５２の位置決めをし、開口部３２、３３を介して外装缶２１及び封口缶２２に固定されている。【選択図】図３
