Abstract: A pressure sensitive adhesive composition containing: a (meth)acrylic ester polymer including butyl methacrylate and a reactive functional group-containing monomer as monomer units that constitute the polymer; and an inorganic filler, a pressure sensitive adhesive obtained by crosslinking the pressure sensitive adhesive composition, and a pressure sensitive adhesive sheet comprising at least a pressure sensitive adhesive layer that is formed from the above pressure sensitive adhesive composition. The above pressure sensitive adhesive composition allows the inorganic filler to be uniformly dispersed in a short time even when a dispersant is not contained. Moreover, in the above pressure sensitive adhesive and the pressure sensitive adhesive layer of the pressure sensitive adhesive sheet, the inorganic filler is uniformly dispersed.
