Beschreibung
Zusammenfassung:	The present invention provides an optical adhesive sheet suitable for a flexible device. An adhesive sheet 10 of the present invention is an optical adhesive sheet containing a base polymer and has a gel fraction of 85% or more and 95% or less. Among sol components of the base polymer in the adhesive sheet 10, the proportion of components having a molecular weight of 500,000 or less is 70% by mass or more. The base polymer is a polymer containing a monomer component of (meth)acrylic acid in an amount of 0.1% by mass or more and 10% by mass or less.
