To provide a medical honeycomb structure which is configured that (1) a tissue missing part can be easily reconstructed, and a medical tissue reconstruction material hardly moves from the tissue missing part, that (2) the material is firmly bonded to a peripheral tissue in embedding in a living body, that (3) a missing tissue reconstruction rate is high in the tissue missing part, and that (4) the medical honeycomb structure satisfies required characters of a medical material that shows an orientation inducing ability to the peripheral tissue, or the like for using in a tissue reconstruction method, scaffold of regenerative medicine, or the like, a forming mold, a related material, and a manufacturing method.SOLUTION: A medical honeycomb structure including a plurality of through-holes extending in one direction is characterized that at least part of an outer peripheral side wall is missing, there are a plurality of grooves in the area where the outer peripheral side wall is missing, and a plurality of flat surfaces that include a distal surface of a groove side wall sandwiched between the grooves are provided.SELECTED DRAWING: Figure 13 【課題】（１）簡便に組織欠損部を再建でき、組織欠損部から医用組織再建材が移動されにくい、（２）生体内に埋入した際に、該材料が周囲組織と強固に結合する、（３）組織欠損部における欠損組織再建率が大きい、（４）周囲組織に対して配向誘導能を示すなどの組織再建術に用いられる医用材料や、再生医療のスキャッフォールドなどの所要性質を満たす医用ハニカム構造体、成形型、関連材料、および製造方法を提供する。【解決手段】一方向に延びる複数の貫通孔を備えたハニカム構造体の、少なくとも一部の外周側壁が欠損し、外周側壁が欠損した部位に複数の溝を備え、該溝に挟まれる溝側壁の遠心面を含む平面を複数備えることを特徴とする医用ハニカム構造体などを提供する。【選択図】図１３
