    Abstract: Provided is a PSA sheet capable of suitably preventing bubble formation caused by outgassing. This invention provides a PSA sheet comprising a PSA layer that forms an adhesive face. In an aging test where the adhesive face is press-bonded to a glass plate and stored at 50° C. for 24 hours, the PSA sheet has at least 5% post-aging non-bonding area Sa, with Sa defined as the ratio of all areas non-bonding to the glass plate relative to the total area of the adhesive face. The non-bonding areas have parts linearly extending along the adhesive face.

    Abstract: The present invention relates to a pressure-sensitive adhesive product including a substrate and at least two point-like pressure-sensitive adhesives on the substrate, wherein an area ratio is from 10 to 60%. The area ratio (%) is a proportion of an area occupied by said point-like pressure-sensitive adhesives per unit area of the substrate. The pressure-sensitive adhesive product is excellent in re-peelability. In addition, the present invention also relates to a fixation method of components, including transferring the point-like pressure-sensitive adhesives in the pressure-sensitive adhesive product to a first component, and then fixing the first component to a second component.
