To suppress problems accompanying contraction of a heat insulation material, and to achieve further improvement in a heat insulation property.SOLUTION: A manufacturing method of a building material includes: a molding step of molding a shape material 1' which has a first building material element 1A and a second building material element 1B connected with each other via a connection part 13, in which cavities 20 are provided respectively at portions which are on both sides sandwiching the connection part 13, and an opening 21 for injection is provided at a portion opposing to the connection part 13 on a peripheral wall constituting each of the cavities 20; a first filling curing step of filling a heat insulation material 1C' in a fluid state in one of the cavities 20 via the opening 21 for injection and curing it; a cutting step of cutting the connection part 13 so that the first building material element 1A and the second building material element 1B are separated; and a second filling curing step of filling the heat insulation material 1C' in a fluid state in the other of the cavities 20 via the opening 21 for injection in a state of coming into contact with the heat insulation material 1C filled in one of the cavities 20 and curing it.SELECTED DRAWING: Figure 4 【課題】断熱材の収縮に伴う問題を抑えた上で更なる断熱性の向上を図ること。【解決手段】連結部１３を介して互いに連結された第１建材要素１Ａ及び第２建材要素１Ｂを有し、連結部１３を挟んで両側となる部分にそれぞれキャビティ２０が設けられるとともに、キャビティ２０のそれぞれを構成する周壁において連結部１３に対向する部分に注入用開口２１が設けられた形素材１′を成形する成形工程と、注入用開口２１を介してキャビティ２０の一方に流動状態の断熱材１Ｃ′を充填して硬化させる第１の充填硬化工程と、第１建材要素１Ａ及び第２建材要素１Ｂが離隔するように連結部１３を分断する分断工程と、キャビティ２０の一方に充填した断熱材１Ｃに接触する状態で注入用開口２１を介してキャビティ２０の他方に流動状態の断熱材１Ｃ′を充填して硬化させる第２の充填硬化工程とを含んでいる。【選択図】図４
