PROBLEM TO BE SOLVED: To provide a shaping sheet for shaping a retroreflection artificial leather sheet using retroreflection, capable of reflecting light without using a particle.SOLUTION: A shaping sheet includes a base material layer (31) and a plurality of projections (32a) formed on one side of the base material layer. A projection has a triangular pyramid shape, with two of three faces intersecting at its apex at a right angle to each other, and enables formation of a corner cube shape.SELECTED DRAWING: Figure 5 【課題】粒子を用いることなく光を反射させることができる再帰反射を用いた再帰反射人工皮革シートを賦型するための賦型シートを提供する。【解決手段】基材層（３１）と、基材層の一方の面に設けられた複数の凸部（３２ａ）と、を有し、凸部は、その頂点に於いて交叉する３面のうちの２面が互いに直角である三角錐状でありコーナーキューブ形状を形成可能な形状とされている。【選択図】図５
