    • A pressure-sensitive adhesive sheet that can be beautifully adhered to an adherend. The pressure-sensitive adhesive sheet (A) is characterized by the following. The sheet has a sheetlike base material (1) and, integrally superimposed on one major surface of the base material (1), a pressure-sensitive adhesive layer (2).The adhesive layer (2) on its surface has multiple corrugated groove portions (3) consisting of alternate continuation of convex circular arc groove portion (31) and concave circular arc groove portion (32). The multiple corrugated groove portions (3) are provided at intervals in the direction of the amplitude of the corrugated groove portions (3). Providing that any arbitrary two corrugated groove portions being adjacent to each other in the direction of the amplitude of the corrugated groove portions (3) consist of the one corrugated groove portion (3a) and the other corrugated groove portion (3b), the total wavelength (S 1 ) of convex circular arc groove portion (31a) and concave circular arc groove portion (32a) of the one corrugated groove portion (3a) is different from the total wavelength (S 2 ) of convex circular arc groove portion (31b) and concave circular arc groove portion (32b) of the other corrugated groove portion (3b), which convex circular arc groove portion (31b) and concave circular arc groove portion (32b) respectively correspond to the convex circular arc groove portion (31a) and concave circular arc groove portion (32a) constructing the one corrugated groove portion (3a).
    • 可以美丽地粘附到被粘物上的压敏粘合剂片。 压敏粘合片(A)的特征如下。 所述片材具有片状基材(1),并且在所述基材(1)的一个主表面上整体地叠置有压敏粘合剂层(2)。所述粘合剂层(2)在其表面上具有多个波纹状沟槽部分 (3)由凸形圆弧凹槽部分(31)和凹形圆弧凹槽部分(32)的交替延续部分组成。 多个波纹状槽部(3)在波纹状槽部(3)的振幅方向上隔开间隔地设置。 如果在波纹槽部分(3)的振幅方向上彼此相邻的任意两个波纹槽部分由一个波纹槽部分(3a)和另一个波纹槽部分(3b)组成,则总波长 (3a)的凸圆弧槽部(31a)和凹圆弧槽部(32a)的凸部(S 1)与凸圆弧槽部(31b)的总波长(S 2) 和另一个波纹槽部分(3b)的凹形圆弧形凹槽部分(32b),该凸形圆弧凹槽部分(31b)和凹形圆弧凹槽部分(32b)分别对应于凸形圆弧凹槽部分(31a)和 形成一个波纹槽部分(3a)的凹形圆弧槽部分(32a)。
