Abrégé
(EN)
An adhesive sheet (1) comprising a base (11) and an adhesive layer (12) is provided with a plurality of through holes (2) which penetrate the adhesive sheet from one surface to the other surface. The diameters of the through holes (2) are 0.1-300 μm, and the hole density is 30-50,000 holes per 100 cm2. These through holes (2) are preferably formed by laser machining. This adhesive sheet (1) enables prevention or removal of an air pocket and a blister while securing sufficient adhesion without deteriorating the appearance.
(FR)
L'invention concerne une feuille adhésive (1) qui comprend une base (11) et une couche adhésive (12) et qui est pourvue d'une pluralité de trous traversants (2) qui traversent la feuille adhésive d'une surface à l'autre. Les diamètres des trous traversants (2) vont de 0,1 à 300 $g(m)m et la densité des trous est de 30 à 50.000 trous par 100 cm2. Ces trous traversants (2) sont de préférence formés par usinage laser. Cette feuille adhésive (1) permet de prévenir ou d'éliminer la formation de poches d'air ou de boursouflures tout en assurant une adhésion suffisante sans détériorer l'apparence.
(JA)
 基材11と粘着剤層12とを備えた粘着シート1に、一方の面から他方の面に貫通する貫通孔2を複数形成する。貫通孔2の孔径は0.1~300μmとし、孔密度は30~50,000個/100cmとする。このような貫通孔2は、レーザ加工によって形成するのが好ましい。かかる粘着シート1によれば、粘着シート1の外観を損なうことなく、かつ十分な接着力を確保しつつ、空気溜まりやブリスターを防止または除去することができる。
