To provide a silicone-made member for fluid device excellent in both handleability and releasability from a form block, and to provide a production method therefor.SOLUTION: A member 20 for fluid device is made by silicone, and a second face 220 is harder than a first face 210 when defining the face of a side having a recess and contacting a fluid among two faces in a thickness direction as the first face 210, and the face of a side opposite to the first face 210 as the second face 220. One of the production method for the member 20 for fluid device comprises: a first hardening process of hardening a first liquid silicone material; and a second hardening process of arranging a second liquid silicone material whose hardness after hardening is different from that of a hardened material of the first liquid silicone material on the surface of the above hardened material, and then hardening the second liquid silicone material.SELECTED DRAWING: Figure 1 【課題】 取り扱い性と成形型からの離型性とが共に優れるシリコーン製の流体デバイス用部材、およびその製造方法を提供する。【解決手段】 流体デバイス用部材２０は、シリコーン製であり、厚さ方向の二つの面のうち、凹部を有し流体が接触する側の面を第一面２１０、第一面２１０と反対側の面を第二面２２０とすると、第二面２２０の硬さは、第一面２１０の硬さよりも大きい。流体デバイス用部材２０の製造方法の一つは、第一の液状シリコーン材料を硬化する第一硬化工程と、該第一の液状シリコーン材料の硬化物の表面に、硬化後の硬さが該硬化物とは異なる第二の液状シリコーン材料を配置して、該第二の液状シリコーン材料を硬化する第二硬化工程と、を有する。【選択図】 図１
