Abstract:
Provided is a PSA sheet with which good air release properties can be obtained while whose quality can be further enhanced. This invention provides a PSA sheet comprising a substrate film and a PSA layer provided to at least one face of the substrate film. The PSA sheet further comprises a coating layer partially covering the PSA layer surface. The PSA sheet's adhesive is formed of the PSA layer and the coating layer. The coating layer has a linearly extending part running from one edge to another edge of the adhesive face. The linearly extending part has a first face forming the PSA sheet's adhesive face and a second face located on the PSA layer side relative to the first face. The second face of the linearly extending part forms an overall gently curved line in a cross section perpendicularly intersecting the length direction of the linearly extending part.
