PROBLEM TO BE SOLVED: To provide a recessed pattern mold which improves a degree of filling accuracy of a liquid to a needle-like recess and a degree of accuracy for positioning a mold, a method of manufacturing a recessed pattern mold, and a method of manufacturing a pattern sheet.SOLUTION: A recessed pattern mold 58 in which a plurality of needle-like recesses are arranged in the form of an array. The recessed pattern mold 58 is a laminate of two or more layers including a first resin and a second resin different from the first resin. In the recessed pattern mold 58, in a thickness direction of the recessed pattern mold, a back surface side of the needle-like recesses comprises the first resin of lower viscosity compared to the second resin, and a needle-like recess side comprises the second resin having higher elongation properties compared to the first resin. In addition, a method of manufacturing the recessed pattern mold 58 and a method of manufacturing a pattern sheet using the recessed pattern mold 58 are provided.SELECTED DRAWING: Figure 10 【課題】針状凹部への液の充填精度、および、モールドの位置決め精度を向上させた凹状パターンモールド、凹状パターンモールドの製造方法、および、パターンシートの製造方法を提供する。【解決手段】複数の針状凹部がアレイ状に配置された凹状パターンモールド５８であって、凹状パターンモールド５８は、第１の樹脂と、第１の樹脂と異なる第２の樹脂と、を含む２層以上の積層体であり、凹状パターンモールドの厚み方向で、針状凹部の裏面側は、第２の樹脂と比較し粘着性の低い第１の樹脂からなり、針状凹部側は、第１の樹脂と比較し高伸び性の第２の樹脂からなる凹状パターンモールド５８である。また、この凹状パターンモールド５８の製造方法、および、凹状パターンモールド５８を用いたパターンシートの製造方法である。【選択図】図１０
