To provide a vehicle body lateral structure and a manufacturing method of the vehicle body lateral structure characterized in that occurrence of electric corrosion is further inhibited compared with an existing technology.SOLUTION: A vehicle body lateral structure includes a side panel outer piece 2 made of an aluminum alloy, a steel side sill stiffener 25 that is located inside in a vehicle width direction of the side panel outer piece 2 and includes a stiffener longitudinal wall 25c located below the side panel outer piece 2, a steel extension piece 5 that is joined to the lower end of the side panel outer piece 2 to form a first joint 31, is joined to the stiffener longitudinal wall 25c of the side sill stiffener 25 to form a second joint 32, and thus links the side panel outer piece 2 to the side sill stiffener 25, and a sack-like cross-section part 7 formed being surrounded by the side panel outer piece 2, side sill stiffener 25, and extension piece 5.SELECTED DRAWING: Figure 5

    【課題】従来技術と比較して、電食の発生を一層抑制した車体側部構造及び車体側部構造の製造方法を提供する。【解決手段】アルミニウム合金製のサイドパネルアウタ2と、サイドパネルアウタ2より車幅方向の内側に設けられ、サイドパネルアウタ2より下方に位置するスチフナ縦壁部25cを含む鋼製のサイドシルスチフナ25と、サイドパネルアウタ2の下端部と接合されて第一接合部31を形成するとともに、サイドシルスチフナ25のスチフナ縦壁部25cと接合されて第二接合部32を形成することにより、サイドパネルアウタ2とサイドシルスチフナ25とを連結する鋼製の延長片5と、サイドパネルアウタ2、サイドシルスチフナ25及び延長片5に囲まれて形成される袋断面部7と、を備える。【選択図】図5
