To provide a manufacturing apparatus capable of enabling mass-production of a power storage device in which a resin layer is stably formed on an accurate position on a side surface of a lamination electrode body.SOLUTION: A manufacturing apparatus provided by the present invention, comprises a resin filling mold that includes an internal space in which a lamination electrode body 80 is housed, and can supply a light hardening resin material 92 for forming a resin layer on a side surface of at least long side of the electrode body. The mold includes: an upper mold and a lower mold; and two side surface molds 40 on the long side. Also, the manufacturing apparatus comprises a light irradiation device 2 that irradiates a light for hardening the resin material supplied into the internal space of the resin filling mold. When a tip end part 94 floating along a side surface of the electrode body of the resin material supplied into the internal space reaches a predetermined position of the side surface, the floating tip end part is hardened by irradiating a light from the light irradiation device to the floating tip end part, and the floating along the side surface of the floating tip end part is stopped.SELECTED DRAWING: Figure 6B 【課題】積層電極体の側面における正確な位置に樹脂層が安定的に形成された蓄電デバイスを量産し得る製造装置の提供。【解決手段】本発明により提供される製造装置は、積層電極体８０が収容される内部空間を有し、該電極体の少なくとも長辺側の側面に樹脂層を形成するための光硬化樹脂材料９２を供給可能に構成された樹脂充填型を備える。該型は、上型および下型と、上記長辺側の２つの側面型４０とを具備する。また、当該製造装置は、上記樹脂充填型の内部空間に供給された上記樹脂材料を光硬化させる光を照射する光照射器２を備える。上記内部空間に供給された上記樹脂材料のうちの上記電極体の側面に沿って流動する先端部分９４が該側面の所定の位置に到達した際に、該流動先端部分に上記光照射器から光を照射して該流動先端部分を硬化させ、該流動先端部分の該側面に沿った流動を停止させるように構成されている。【選択図】図６Ｂ
