In the exterior body, at least one conduction portion 17 on the first thermoplastic resin layer 15 side exists regardless of the form of the exterior body, and serves as a first inner conduction portion facing the electrode element chamber. Moreover, when it has the 2nd conduction | electrical_connection part 17, it becomes the 1st outer side conduction | electrical_connection part of an exterior body outer surface. On the other hand, the conductive portion 16 on the first heat-resistant resin layer 13 side may or may not exist depending on the form of the exterior body. If present, it is formed on the outer surface of the exterior body and becomes the first outer conductive portion. .

A plastic resin layer 25 is laminated and laminated. On the surface of the second heat resistant resin layer 23 side, there is formed a conducting portion 26 that is exposed to the second metal foil 21 without the second heat resistant resin layer 23 and the adhesive layer 22 and the second metal foil 21 is exposed. ing. On the surface of the second thermoplastic resin layer 25 side, there is formed a conducting portion 27 where the second metal foil 21 is exposed without the second thermoplastic resin layer 25 and the adhesive layer 24. In the exterior body, at least one conduction portion 27 on the second thermoplastic resin layer 25 side exists regardless of the form of the exterior body, and serves as a second inner conduction portion facing the electrode element chamber. Moreover, when it has the 2nd conduction | electrical_connection part 27, it becomes the 2nd outer side conduction | electrical_connection part of the outer surface of an exterior body. On the other hand, the conductive portion 26 on the second heat-resistant resin layer 23 side may or may not exist depending on the form of the exterior body. If present, it is formed on the outer surface of the exterior body and becomes the second outer conductive portion. .

なお、図3Bおよび図8は、接着剤層12、14、22、24の図示を省略して第一耐熱性樹脂層13、第二耐熱性樹脂層23、第一金属箔11、第二金属箔層21、第一熱可塑性樹脂層15、第熱可塑性樹脂層25のみを図示している。
(第1の蓄電デバイス)
図2〜図3Bに示すように、蓄電デバイス1の外装体30は、第一外装材10からなり平面視長方形の凹部41を有する本体40と、第二外装材20からなるフラットシートの蓋体50とにより構成され、本体40の凹部41に蓋体50を被せることにより閉鎖される空間が電池要素室60となる。
3B and 8, the illustration of the adhesive layers 12, 14, 22, and 24 is omitted, and the first heat-resistant resin layer 13, the second heat-resistant resin layer 23, the first metal foil 11, and the second metal Only the foil layer 21, the first thermoplastic resin layer 15, and the second thermoplastic resin layer 25 are shown.
(First power storage device)
As shown in FIG. 2 to FIG. 3B, the exterior body 30 of the electricity storage device 1 is a flat sheet lid body composed of a first exterior member 10 and a main body 40 having a rectangular recess 41 in plan view, and a second exterior member 20. 50, and a space that is closed by covering the concave portion 41 of the main body 40 with the lid 50 is the battery element chamber 60.

前記蓄電デバイス2、3は、第一外側導通部82、85と第二外側導通部56、52とが外装体31、32の同じ辺に蓋体50側を向いて設けられており、第一外側導通部47と第二外側導通部52を外装体30の対向辺に設けた蓄電デバイス1よりも両者が近接している。両者の近接により、集電用回路の構造のさらなる単純化および小型化を図ることができる。特に図の蓄電デバイスは第一外側導通部82と第二外側導通部56とが辺の長さを二分して設けられているので、導通用フランジの熱封止部61からの延出長さを小さくできるので、蓄電デバイスそのものを小型化でき、ひいては集電用回路を小型化することができる。 In the electricity storage devices 2 and 3, the first outer conducting portions 82 and 85 and the second outer conducting portions 56 and 52 are provided on the same side of the exterior bodies 31 and 32 so as to face the lid 50 side. Both are closer than the electricity storage device 1 in which the outer conductive portion 47 and the second outer conductive portion 52 are provided on opposite sides of the exterior body 30. Due to the proximity of both, the structure of the current collecting circuit can be further simplified and miniaturized. In particular, in the electricity storage device 2 of FIG. 4 , the first outer conductive portion 82 and the second outer conductive portion 56 are provided by dividing the length of the side into two, so that the conductive flange extends from the heat sealing portion 61. Since the length can be reduced, the power storage device itself can be reduced in size, and thus the current collecting circuit can be reduced in size.
