Provided is a metal composite material which contains an adhesive layer and has superior rigidity than conventional metal composite materials. In this metal composite material (10), the sheet thickness (h1) of a thin steel sheet (1) and the sheet thickness (h2) of a low-specific-gravity sheet material (2) are set so as to satisfy the following numerical formula (1) that represents the bending rigidity [D] of the metal composite material (10) that has been set in advance: "numerical formula 1" imgabs0 # (in numerical formula (1), b is the width of the metal composite material (1), E1 is the longitudinal elastic coefficient of the thin steel sheet (1), E2 is the longitudinal elastic coefficient of the low-specific-gravity sheet material (2), and the thickness (h2) of the low-specific-gravity sheet material (2) is the thickness (h1) of the thin steel sheet (1). V1 is the Poisson's ratio of the thin steel plate (1), v2 is the Poisson's ratio of the low-specific-gravity sheet material (2), h1 is the sheet thickness of the thin steel plate (1), h2 is the sheet thickness of the low-specific-gravity sheet material (2), h3 is the thickness of the adhesive layer (3), h0 is the thickness of the adhesive layer (3) from the bonding interface between the low-specific-gravity sheet material (2) and the adhesive layer (3) to the neutral axis (Ax), and h1 and h2 satisfy the relationship h1 < h2.
