Zusammenfassung:To provide a retroreflective sheet which is easy in manufacturing, and by which a pattern formed of an ink layer can be clearly and visually confirmed.SOLUTION: In a retroreflective sheet (101) having a retroreflective laminate (10) and a visible ink layer (21), the retroreflective laminate (10) has a reflection material layer (12) and a transparent spherical body laminate (11), the transparent spherical body laminate (11) has a plurality of transparent spherical bodies, at least a part of the transparent spherical bodies is imbedded into the reflection material layer (12), and the visible ink layer (21) covers at least a part of portions of the followings (i) and (ii), and does not cover apexes of a plurality of the transparent spherical bodies. In the retroreflective sheet (101), (i) the portion is that other than the apexes of a plurality of the transparent spherical bodies, and (ii) the portion is that of the reflection material layer (12) in a clearance of a plurality of the transparent spherical bodies.SELECTED DRAWING: Figure 1 【課題】製造が容易であり、インキ層によって形成される絵柄を、鮮明に視認できる再帰反射性シートを提供すること。【解決手段】再帰反射性積層体(10)及び可視インキ層(21)を有する再帰反射性シート(101)であって、再帰反射性積層体(10)は、反射材層(12)及び透明球状体層(11)を有し、透明球状体層(11)は複数の透明球状体を有し、各透明球状体は少なくとも一部が反射材層(12)に埋め込まれており、可視インキ層(21)は、下記(i)及び(ii)の部分の少なくとも一部を被覆しており、かつ前記複数の透明球状体の頂部を被覆していない、再帰反射性シート(101):(i)複数の透明球状体上の頂部以外の部分、及び(ii)複数の透明球状体の間隙の反射材層(12)の部分。【選択図】図1
