The light-blocking sheet (11), which is an adhesive sheet, is mainly configured from a sheet (20) obtained from PET, etc. and an adhesive layer (31) that is formed on the underside of the sheet (20) and is obtained from a silicone adhesive. Slits (41) formed so as to pierce the light-blocking sheet (11) are configured from a first linear part (51), and a pair of second linear parts (52a, 52b) and a pair of third linear parts (53a, 53b) that extend respectively from the two ends of the first linear part (51). Because such slits (41) are configured so as not to overlap lines, represented by the dashed lines, which tie the one ends thereof with the other ends, the outward opening of each of the areas (65a - 65d) configured by the lines represented by the dashed lines and the slit (41) is facilitated. Consequently, during adhesion, escape of air between the light-blocking sheet (11) and the adherend is facilitated and because the opened areas subsequently return to the original state, light-blocking properties are not reduced. |
