(57) [Abstract] [PROBLEMS] To provide a laminate having excellent antistatic properties and a lid material having high adhesion to a synthetic resin container, good peelability, and excellent electrostatic properties. And A heat resistant base material layer, an adhesive layer, an intermediate layer and a heat sealant layer are laminated in this order to form a laminate, and an initial impact strength P by a loop stiffness method is 5 g. To 20 g, the stiffness strength f is less than or equal to the initial impact strength P, the stiffness strength f and the elapsed time t after the start of measurement (t is 3 minutes or more) are in a proportional relationship, and the proportional constant a is −0. It is assumed that 1 ≦ a <0 is satisfied. |
