To provide a vehicle body reinforcement structure capable of suppressing weight increase and enhancing rigidity, and a production method thereof.SOLUTION: A reinforcement structure of a back door 10 is configured so that an inner panel 21 and an outer panel 31 are adhered by a high rigidity foam adhesive member 61 penetrating a first through hole 42a of a first reinforcement 41 and a second through hole 52a of a second reinforcement 51. In the reinforcement structure of the back door 10, the high rigidity foam adhesive member 61 is filled between the outer panel 31 and the second reinforcement 51, between the second reinforcement 51 and the first reinforcement 41, and between the first reinforcement 41 and the inner panel 21.SELECTED DRAWING: Figure 2

    【課題】重量増加を抑制しつつ剛性を高めることができる車体補強構造、及び車体補強構造の製造方法を提供すること。【解決手段】バックドア10の補強構造において、第1リインフォースメント41の第1貫通孔42a及び第2リインフォースメント51の第2貫通孔52aを貫通している高剛性発泡接着部材61によってインナパネル21とアウタパネル31とが接着されている。また、バックドア10の補強構造において、アウタパネル31と第2リインフォースメント51との間、第2リインフォースメント51と第1リインフォースメント41の間、及び第1リインフォースメント41とインナパネル21との間に高剛性発泡接着部材61が充填されている。【選択図】図2
