To improve the insulation property without inviting problems such as leakage.SOLUTION: A cavity constituent part 10 of a first construction material element 1A and a cavity constituent part 10 of a second construction material element 1B have base wall parts 11 facing each other, inner peripheral wall parts 12 projecting from a position corresponding to the inner periphery of the base wall parts 11 in the direction in which the inner peripheral wall parts approach each other, and outer peripheral wall parts 12 projecting from a position corresponding to the outer periphery of the base wall parts 11 in the direction in which the outer peripheral wall parts 12 approach each other, inner protruding parts 14 having a flat plate shape so as to be embedded inside a heat insulating material 1C project from the respective base wall parts 11 in the direction in which the inner protruding parts 14 approach each other, the projection dimension d4 of the inner protruding parts 14 from the base wall parts 11 is shorter than the projection dimension of the inner peripheral wall parts 12 and the projection dimension of the outer peripheral wall parts 12, and a gap d2 of at least three times the plate thickness of the inner protruding parts 12 is secured between the inner peripheral wall parts 12 and the outer peripheral wall parts 12.SELECTED DRAWING: Figure 3 【課題】漏水等の問題を招来することなく断熱性の向上を図る。【解決手段】第１建材要素１Ａのキャビティ構成部１０及び第２建材要素１Ｂのキャビティ構成部１０は、互いに対向する基壁部１１と、基壁部１１の内周となる位置から互いに近接する方向に突出した内周壁部１２と、基壁部１１の外周となる位置から互いに近接する方向に突出した外周壁部１２とを有し、それぞれの基壁部１１には、断熱材１Ｃの内部に埋め込まれるように平板状を成す内方突出部１４が互いに近接する方向に向けて突出されており、内方突出部１４は、基壁部１１からの突出寸法ｄ４が内周壁部１２の突出寸法及び外周壁部１２の突出寸法よりも短く、内周壁部１２と外周壁部１２との間には、内方突出部１４の板厚の３倍以上の隙間ｄ２が確保されている。【選択図】図３
