To provide a method for manufacturing a laminate type battery, with which it is possible to weld a laminated outer packaging appropriately while a terminal is protruded outward from the inside.SOLUTION: The method for manufacturing a laminate type battery includes a preparation step and a welding step. In the preparation step, an assembly is prepared, in which a power generating element is arranged between a pair of wide faces of a laminated outer packaging 30 while a terminal 20 is protruded outward. In the welding step, while a heat compression member 60 formed with a material having heat resistance and elasticity and equipped with a pressure chamber 61 into which a pressurized fluid is introduced, is brought into contact with the assembly, an edge 31 of the laminated outer packaging 30 that sandwiches the terminal 20 is welded. In the welding step, the pressure chamber 61 of the heat compression member 60 is placed in a state of facing an end of a portion of the edge 31 in an extension direction L where the terminal 20 is located, and a pressurized fluid is introduced into the pressure chamber 61 and the edge 31 is heated while being compressed.SELECTED DRAWING: Figure 3 【課題】端子を内部から外方に突出させた状態で、ラミネート外装体を適切に溶着することが可能なラミネート型電池の製造方法を提供する。【解決手段】ラミネート型電池の製造方法は、準備工程および溶着工程を含む。準備工程では、ラミネート外装体３０の一対の幅広面の間に、端子２０を外方に突出させた状態で発電要素が配置されたアセンブリが準備される。溶着工程では、耐熱性および弾性を有する材質によって形成され、且つ加圧された流体が導入される加圧室６１を備える加熱圧縮部材６０を、アセンブリに接触させた状態で、ラミネート外装体３０のうち端子２０を挟み込む縁部３１が溶着される。溶着工程では、加熱圧縮部材６０の加圧室６１を、縁部３１の伸長方向Ｌのうち端子２０が位置する部位の端部に対向させた状態で、加圧された流体を加圧室６１に導入して縁部３１を圧縮しつつ、縁部３１を加熱する。【選択図】図３
