- a U-shaped groove force S with a width of 180 111 and a depth of 50 111 is formed in a lattice pattern with a pitch of 360 m, and the surface is subjected to uneven processing with a convex part that is a square with a side of 180 m.
- a pressure-sensitive adhesive sheet was obtained in the same manner as in Example 1 except that an ethylene′-butyl acetate copolymer having a thickness of 100 m and a tensile modulus of 210 MPa was used.
- the resulting pressure-sensitive adhesive sheet was subjected to an air retention disappearance test and a blister resistance test, and the results are shown in Table 1.
- a pressure-sensitive adhesive sheet was obtained in the same manner as in Example 1, except that the surface was subjected to uneven processing and used a polyethylene terephthalate sheet having a normal thickness of 50 ⁇ m.
- the resulting pressure-sensitive adhesive sheet was subjected to an air retention disappearance test and a blister resistance test, and the results are shown in Table 1.
- the pressure-sensitive adhesive sheet of the present invention is particularly suitable as a large-sized pressure-sensitive adhesive sheet, such as a pressure-sensitive adhesive sheet for decoration, a pressure-sensitive adhesive sheet for coating masking, and a pressure-sensitive adhesive sheet for surface protection such as a metal plate.
