PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive laminate comprising an outside film layer, an adhesive base layer and a tackifier layer improved in properties and in manufacturing method. SOLUTION: The pressure-sensitive adhesive laminate comprises (a) at least one outer film layer (A) containing at least one filmic polymer, (b) at least one adhesive base layer (B) containing at least one adhesive base polymer and (c) at least one tackifier layer (C) containing at least one tackifier and at least one polymer, wherein the pressure-sensitive adhesive (PSA) laminate described above is characterized by forming a non-adhesive laminate by simultaneously extruding (co-extruding) the outer film layer (A) together with the adhesive base layer (B) to produce the non-adhesive laminate and by applying the tackifier layer to the adhesive base layer side of the non-adhesive laminate to produce the PSA laminate.
