To fold an exterior coating body while suppressing damages due to a heat to a power generation element.SOLUTION: A manufacturing method of a laminate type battery, comprises: a power generation element; and an exterior coating body into which the power generation element is formed by a laminate film and is included so as to be closed to a center from a peripheral edge part. The manufacturing method of the laminate type battery, includes: a first step of making a metal round wire contact with one part of the peripheral edge part of the exterior coating body; and a second step of folding the peripheral edge part of the exterior coating body to one surface side as using the metal round wire as a guide while heating the metal round wire. Thus, the exterior coating body can be folded while suppressing damages to a heat to the power generation element.SELECTED DRAWING: Figure 4 【課題】発電要素へ熱によるダメージを抑制しながら外装体を折り曲げる。【解決手段】発電要素と、ラミネートフィルムから形成され周縁部よりも中央寄りに発電要素が封入されている外装体と、を備えるラミネート型電池の製造方法であって、外装体の周縁部の一面の一部に金属丸線を当接させる第１工程と、金属丸線を加熱しながら、金属丸線をガイドとして、外装体の周縁部を一面側に折り曲げる第２工程と、を備える。これにより、発電要素へ熱によるダメージを抑制しながら外装体を折り曲げることができる。【選択図】図４
