To provide a hot press device capable of excellently suppressing that variation occurs on a molded body acquired when a plurality of molded bodies are formed at the same time.SOLUTION: A hot press device includes a pair of press board parts having a mold which contains a pressing surface provided with a plurality of cavities for molding. Therein, at least one press board part further includes a heating part which heats the mold and a heat conduction control part located between the mold and the heating part, the heat conduction control part is configured such that a flat surface view center part has at least one heat conduction layer, flat surface view end parts have at least two heat conduction layers having heat conductivities in the thickness direction different from each other, and the flat surface view end parts have higher heat conductivity in the thickness direction than the flat surface view center part.SELECTED DRAWING: Figure 1 【課題】複数の成形体を同時に形成した際に得られる成形体にバラつきが発生するのを良好に抑制し得る熱プレス装置を提供する。【解決手段】複数の成形用キャビティが設けられた加圧面を含む金型を有する一対のプレス盤部を備え、少なくとも一方のプレス盤部は、金型を加熱する加熱部と、金型と加熱部との間に位置する熱伝導調節部とを更に有し、熱伝導調節部は、平面視中央部が、少なくとも１層の熱伝導層を有し、平面視端部が、厚み方向の熱伝導率が互いに異なる少なくとも２層の熱伝導層を有し、且つ、前記平面視端部が、平面視中央部よりも厚み方向の熱伝導率が高い、熱プレス装置。【選択図】図１
