PROBLEM TO BE SOLVED: To form a laminate having superior antistatic property and characteristic, and a lid material combining a stable adhesiveness, good peelability and excellent antistatic effect by providing a static despersive layer consisting of conductive minute grains and a binder on one surface of a heat seal resin layer. SOLUTION: A heat seal resin layer 2 forming a heat seal layer 1 is made up of an ethylene vinyl acetate copolymer, a hotmelt adhesive consisting mainly of olefin, elastomer or the like, etc. The static dispersive layer 3 formed on one surface of the heat seal layer 1 is made such that coat liquid with minute grains such as conductive minute grains of tin oxide or the like or minute grains such as an organic silicone compound dispersed in a vehicle is coated by a gravure reverse method. The conductive minute grain have preferably a primary average grain diameter of, e.g. 0.01-10μm, and can form a laminate having a rate of surface resistance of 10<8> -10<12>Ω/square. Material used for a binder of the static dispersive layer 3 is preferable to be polyester, urethane, acrylic resin or the like.
