PROBLEM TO BE SOLVED: To provide a multilayer structure elastomer molded article or a weather strip in which bleeding is suppressed in a coating body formed on a surface of a substrate and desired sliding property and wear resistance are achieved.SOLUTION: A first thermoplastic elastomer material prepared by compounding, kneading and crosslinking at least a rubber component, an olefin resin material, and a crosslinking agent, and a second thermoplastic elastomer material prepared by compounding, kneading and crosslinking at least a rubber component, an olefin resin material, a crosslinking agent, and a lubricant, are molded by extrusion to form a substrate 10 made of the first thermoplastic elastomer material and a coating body 6 made of the second thermoplastic elastomer material is formed on a surface of the substrate 10. Weight percentages A, B of a softening agent included in the first and second thermoplastic elastomer materials, respectively, are controlled to satisfy a ratio B/A of B to A ranging from 0.00 to 0.30; and a crosslinking degree of the coating body is controlled to 90% or more. |
