Zusammenfassung:	To provide a multilayer structure that has incombustibility and resists a dimensional change during heating at high temperature.SOLUTION: A multilayer structure 10 has a metal sheet 12 and a resin body 11. In an exothermic test using a cone calorimeter for heating from the metal sheet 12 side, a test piece 50 mm thick is not in contact with ignition and does not catch fire, with a gross calorific value of 8MJ/m2 or less for 20 minutes.SELECTED DRAWING: Figure 1 【課題】不燃性を有し、かつ高温加熱時の寸法変化を抑制できる積層構成体を提供する。【解決手段】積層構成体１０は、金属シート１２及び樹脂体１１を備え、金属シート１２側から加熱するコーンカロリーメータを用いた発熱性試験において、厚み５０ｍｍの試験体が、イグニッションに接触しないで、かつ、着火しないで、２０分間の総発熱量が８ＭＪ／ｍ２以下である。【選択図】図１
