    Abstract: An article 10 is provided with an adhesive layer 14 that includes an adhesive, a release layer 12 that is stacked on the adhesive layer 14, and an air layer 16 that is interposed between the adhesive layer 14 and the release layer 12. On a surface 12a of the release layer 12 that opposes the adhesive layer 14, microprotrusions 20 that contact the adhesive layer 14 with tips 20a are provided. The microprotrusions 20 are provided with a wall-shaped portion 22 having a shape that at least partially surrounds the air layer 16 between the adhesive layer 14 and the release layer 12. The wall-shaped portion 22 protects a main portion 14a of the adhesive layer 14 that is adjacent to the air layer 16 from contamination. By selecting a shape, dimensions, and the like of the micro protrusions 20, a release force of the release layer 12 can be adjusted to a desired range.
