To provide a release sheet capable of producing a resin article that can exhibit a moist and calm matte texture, and to provide a resin article capable of exhibiting a moist and calm matte texture.SOLUTION: The present disclosure provides a release sheet used for manufacturing a resin article, in which the release sheet 1 comprises a base layer 2 and a resin layer 3 disposed on one side of the base layer. The release sheet has an uneven structure 4 on a surface opposite to the substrate layer, the uneven structure has an irregular structure, and the uneven structure has an arithmetic mean roughness (Sa) of 0.2 μm or more and 0.6 μm or less and a shortest auto-correlation distance (Sal) of 60 μm or more and 200 μm or less.SELECTED DRAWING: Figure 1 【課題】しっとりとして落ち着いたマット調の質感を奏することのできる樹脂製物品を製造可能な離型シート、およびしっとりとして落ち着いたマット調の質感を奏し得る樹脂製物品を提供する。【解決手段】本開示は、樹脂製物品の製造に用いられる離型シートであって、基材層２と、上記基材層の一方の面に配置された樹脂層３と、を有し、上記樹脂層は、上記基材層とは反対側の面に、凹凸構造４を有し、上記凹凸構造は不規則な構造であり、上記凹凸構造は、算術平均粗さ（Ｓａ）が０．２μｍ以上０．６μｍ以下であり、最短の自己相関距離（Ｓａｌ）が６０μｍ以上２００μｍ以下である、離型シート１を提供する。【選択図】図１
