PROBLEM TO BE SOLVED: To provide a nano thin film transfer sheet which can suitably transfer a nano thin film layer.SOLUTION: A nano thin film transfer sheet 1 has a base material 2, and a nano thin film layer 3 provided on the principal face of the base material 2. In plan view from the nano thin film layer 3 side, the base material 2 has a margin region R0. The margin region R0 comprises at least part of an edge 2a of the base material 2 but the nano thin film layer 3 is not present in the margin region.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】ナノ薄膜層を好適に転写できるナノ薄膜転写シートを提供すること。【解決手段】基材2と、基材2の主面上に設けられたナノ薄膜層3とを備え、基材2は、ナノ薄膜層3側からの平面視において、基材2の縁部2aの少なくとも一部を含み且つナノ薄膜層3が存在しない余白領域R0を有する、ナノ薄膜転写シート1。【選択図】図1
