To provide a manufacturing method of a bus bar assembly capable of reliably securing electrical insulation between a plurality of bus bars and capable of efficiently manufacturing bus bar assemblies in which the plurality of bus bars are located on desirable relative positions.SOLUTION: A manufacturing method of a bus bar assembly includes: a process of preparing a first conductive metal flat plate; a process of forming a slit on a bus bar assembly forming region of the flat plate; a process of applying coating material which contains an insulating resin such that at least the slit is filled with an insulating resin layer; a process of forming the insulating resin layer by curing the coating material; and a cutting process of cutting the bus bar forming portions which are opposed so as to sandwich the slit, of the insulating resin layer in the slit and the first conductive metal flat plate from the first conductive metal flat plate.SELECTED DRAWING: Figure 4 【課題】複数のバスバー間の電気的絶縁性を確実に確保でき且つ前記複数のバスバーが所望相対位置に位置されたバスバーアッセンブリを効率良く製造し得るバスバーアッセンブリの製造方法を提供する。【解決手段】本発明に係る製造方法は、第１導電性金属平板を用意する工程と、前記平板のバスバーアッセンブリ形成領域にスリットを形成する工程と、少なくとも前記スリットが絶縁性樹脂層で充填されるように絶縁性樹脂を含む塗料を塗装する工程と、前記塗料を硬化させて絶縁性樹脂層を形成する工程と、前記スリット内の絶縁性樹脂層及び前記第１導電性金属平板のうち前記スリットを挟んで対向するバスバー形成部位を前記第１導電性金属平板から切断する切断工程とを含む。【選択図】図４
