PROBLEM TO BE SOLVED: To produce a retroreflective sheet capable of sufficiently transmitting light without hindrance by retroreflective parts. SOLUTION: In the production of the retroreflective sheet, a dividing line part K is printed on the surface of a temporary fixing layer 7, transparent spheres 2 are embedded in the surface of the layer 7 except the part K and the surface of a fixing layer 4 is brought into contact with the surface of the temporary fixing layer 7. After pressing, the layer 7 is peeled from the layer 4 and the transparent spheres 2 are left on the layer 4. Since the dividing line part K is peeled together with the layer 7 from the layer 4, a light transmissive part 40 with no transparent spheres 2 is disposed on the fixing layer 4. |
