To provide a decoration layered product having an excellent designability, which has a stereoscopic effect.SOLUTION: A decoration layered product 10 includes: a shaping layer 20 having a shaping surface 20a in which an uneven structure 25 is formed; and an intensity control layer 30 covering the shaping surface 20a. The decoration layered product 10 has a unit optical element 13. The unit optical element 13 reflect, refract and/or diffract light which entered into a front-side surface 11 of the decoration layered product 10, according to the uneven structure 25. In the unit optical element 13, a shaping surface 20a includes a plurality of inclined surfaces 26A. A plurality of inclined surfaces 26A are aligned in a direction which goes to a reference line L1, and are inclined towards the reference line L1. A standard deviation of pitch WA1 of the inclined surface 26A adjacent to the reference line is 5 μm or less; a standard deviation of height H26 of the inclined surface 26A adjacent to the reference line is 1 μm or less; the inclined surface 26A adjacent to the reference line is a plurality of inclined surfaces 26A that are located adjacent to the reference line L1 and are continuously aligned toward the reference line L1.SELECTED DRAWING: Figure 4
【課題】立体感を有する優れた意匠性を持つ加飾積層体を提供する。【解決手段】加飾積層体10は、凹凸構造25が形成された賦形面20aを有する賦形層20と、賦形面20aを覆う輝度調整層30とを備えている。加飾積層体10は、単位光学要素13を有する。単位光学要素13は、加飾積層体10の表側面11に入射した光を、凹凸構造25に応じて反射、屈折および/又は回折させる。単位光学要素13において、賦形面20aは、複数の傾倒面26Aを含む。複数の傾倒面26Aは、基準線L1に向かう方向に並び、且つ、基準線L1に向けて傾倒する。基準線近接傾倒面26AのピッチWA1の標準偏差が5μm以下であり、基準線近接傾倒面26Aの高さH26の標準偏差は1μm以下であり、基準線近接傾倒面26Aは、基準線L1に近接して位置し基準線L1に向けて連続して並ぶ複数の傾倒面26Aである。【選択図】図4
