PROBLEM TO BE SOLVED: To obtain a static electricity-proof adhesive laminate which is free from bleed-out, can prevent contamination to an adherend, is stably independent of humidity, and is added with durable static electricity-proof performance. SOLUTION: In the static electricity-proof adhesive laminate comprising a base material layer and a static electricity-proof adhesive layer, the static electricity-proof adhesive laminate is produced by a multilayer coextrusion molding method, and the static electricity-proof adhesive layer contains 50-90 mass% of a mixture comprising a component A: 75-94 mass% of an ethylene-α-olefin copolymer with a density of 0.86-0.91 g/cm<SP>3</SP>which is produced in the presence of a metallocene catalyst, a component B: 5-30 mass% of a soft propylene polymer having an ethylene content of 0-30 mol%, anα-olefine content of 0-30 mol%, and a melting point measured by differential scanning calorimetric analysis below 120°C or unobserved, and a component C: 1-10 mass% of a thermoplastic styrene elastomer and 10-50 mass% of a polyether antistatic agent.
