Abrégé

Disclosed is a retroreflective sheet using a cube-corner type retroreflection principle, which is composed of a body layer which includes a flexible transparent thermoplastic sheet made of a transparent material for high light transmittance and having a smooth surface as a front surface and also includes a woven fabric disposed therein, and a cube-corner type microprism layer having a retroreflective function formed on a surface of the body layer including the transparent thermoplastic sheet and the woven fabric in an integrated form, opposite the front surface. The retroreflective sheet has a configuration in which the woven fabric having high tensile strength is inserted into the transparent thermoplastic polymer (PVC, TPU, PO, or acryl) sheet, and is suitable for end uses requiring high tensile force.
