The present disclosure provides: a multilayer composite for an airbag having excellent durability by controlling softness and adhesiveness between an adhesive layer and a base fabric within specific ranges; and an airbag using the multilayer composite for airbags. A multilayer composite for an airbag according to the present invention comprises: a base fabric; and a multilayer film including an outer layer and an adhesive layer bonded to one surface of the base fabric, the multilayer film being characterized in that the adhesive strength at the interface between the multilayer film and the base fabric is 5 N/cm or more, the difference in the ring stiffness between the multilayer composite for an airbag and the base fabric is 130 mN/cm or less, the adhesive layer containing a first resin having hydrogen bonding ability, and the adhesive layer containing a second resin having hydrogen bonding ability. The difference (HSP) between Hansen solubility parameters of the base fabric and the first resin is 5 MPa 0.5 or less.
