PROBLEM TO BE SOLVED: To provide a laminated body for an extrusion tubular container in which the separation between a barrier layer and a sealant layer does not occur with a volatile component or a liquid component. SOLUTION: For this laminated body 1 for the extrusion tubular container, an outermost layer and an innermost layer are constituted of a heat-sealable thermoplastic resin. At the same time, the laminated body for the extrusion tubular container has a plurality of intermediate layers including at least the barrier layer 4 in a space between the outermost layer and the innermost layer. In the laminated body for the extrusion tubular container, on the surface on the interior side of the barrier layer 4, a coating dry layer of an aqueous dispersed body which consists of a polyolefin copolymeric resin particle, and does not substantially contain a non-volatile auxiliary agent for aquatic transformation is formed as an anchor coating layer 5. In this case, the polyolefin copolymeric resin particle contains an unsaturated carboxylic acid or its anhydride in a range of 0.01 to 5 mass%, and the number-average particle size of which is 1μm or lower.
