To provide a cement hardened body production method which can absorb carbon dioxide with high efficiency, and a cement hardened body.SOLUTION: A cement hardened body production method has: a molding step in which a cement composition is fed to the inside of a formwork to mold intermediate products each having a gas passible passage from either side face to the other side face in rectangular parallelepiped opposite two side faces; and a curing step of storing the plural intermediate products in a curing chamber in a state of being accumulated so that the passages of the respective intermediate products are connected, and carbon dioxide is filled into the curing chamber to execute curing.SELECTED DRAWING: Figure 1 【課題】二酸化炭素を効率良く吸収させることができるセメント硬化体の製造方法、及びセメント硬化体を提供する。【解決手段】セメント硬化体の製造方法は、型枠内にセメント組成物を供給して、直方体状の向かい合う２つの側面のうち一方の側面から他方の側面にわたって気体を通過可能な通路を有する中間品を成形する成形工程と、複数の中間品を各中間品の通路が繋がるように積み重ねた状態で養生室内に収容し、養生室内に炭酸ガスを充満させて養生する養生工程と、を備える。【選択図】図１
