To provide a metal composite material that has an excellent rigidity in comparison with conventional technologies even including an adhesive layer.SOLUTION: According to a metal composite material 10 of the present invention, a thickness h1 of a thin steel sheet 1 and a thickness h2 of a low specific gravity sheet 2 are set so as to satisfy a formula that represents a preset bending rigidity [D] of the metal composite material 10. Moreover, a method for producing a metal composite material includes: a step for preparing the thin steel sheet and the low specific gravity sheet; and a step for joining the thin steel sheet and the low specific gravity sheet with each other via an adhesive layer 3 therebetween. The step for joining the thin steel sheet and the low specific gravity sheet with each other is carried out in such a way that a neutral axis when the metal composite material is bent and deformed is set to be within the adhesive layer that has a lower strength than those of the thin steel sheet and the low specific gravity sheet.SELECTED DRAWING: Figure 2

    【課題】本発明は、接着剤層を含みながらも従来と比べて剛性に優れた金属複合材を提供する。【解決手段】本発明の金属複合材10は、予め設定される金属複合材10の曲げ剛性[D]を表す式を満足するように薄鋼板1の板厚h1及び低比重板材2の板厚h2が設定されていることを特徴とする。また、前記薄鋼板と、前記低比重板材と、を準備する工程と、前記薄鋼板と前記低比重板材とを接着剤層3を介して接合する工程と、を備える金属複合材の製造方法であって、前記薄鋼板と前記低比重板材との接合工程は、前記金属複合材の曲げ変形する際の中立軸が、前記薄鋼板及び前記低比重板材よりも強度の低い前記接着剤層内に設定されるように行うことを特徴とする。【選択図】図2
