PROBLEM TO BE SOLVED: To provide a mold manufacturing method which, even when a reinforcing member to compensate the insufficient rigidity of the mold body is buried, can prevent the thickness of the mold body from increasing and stabilize the height after the burial of the reinforcing member into the mold body.SOLUTION: The mold manufacturing method comprises: a preparation step S1 of preparing, on a base 11, an original plate 28 with a projecting pattern 20A formed thereon, a reinforcing member 16 having openings 16A, and a support plate 24 a spacer arranging step S2 of arranging on the support plate a spacer 30 which locates the reinforcing member in a desired burial position in a thickness direction of the mold body 14 a reinforcing member mounting step S3 of mounting the reinforcing member on the support plate by way of the spacer a mold body forming step S4 of applying a molding liquid resin onto the support plate to form the mold main body a transfer step S6 of clamping the mold body between the original plate 28 and the support plate to transfer a recessed pattern 12 to the positions of the openings of the reinforcing member and a separation step S7 of separating the mold body from the original plate and the support plate after the mold body has cured.SELECTED DRAWING: Figure 13COPYRIGHT: (C)2018,JPO&INPIT【課題】モールド本体の剛性不足を補うために補強材を埋設してもモールド本体の厚みが厚くなるのを抑制でき、モールド本体に対する補強材の埋設高さを安定化させることができるモールドの作製方法を提供する。【解決手段】台11の上に凸状パターン20Aが形成された原版28、開口部16Aを有する補強材16、及び支持板24を準備する準備工程S1、補強材をモールド本体14の厚み方向の所望埋設位置に位置決めするスペーサ30を、支持板の上に配設するスペーサ配設工程S2、補強材をスペーサを介して支持板の上に設置する補強材設置工程S3、支持板の上にモールド用液状樹脂を付与してモールド本体を形成するモールド本体形成工程S4、原版28と支持板とでモールド本体を挟み込んで、補強材の開口部の位置に凹状パターン12を転写する転写工程S6、モールド本体を固化してから原版及び支持板からモールド本体を剥離する剥離工程S7と、を備えた。【選択図】図13
