Abstract
A pressure sensitive adhesive particle includes a styrene resin that contains, as polymerization components, styrene and a vinyl monomer other than styrene; and a (meth)acrylate resin that contains, as polymerization components, at least two (meth)acrylates that account for 90 mass % or more of all polymerization components of the (meth)acrylate resin, in which the pressure sensitive adhesive particle has a sea phase that contains the styrene resin, and island phases that are dispersed in the sea phase and contain the (meth)acrylate resin, the pressure sensitive adhesive particle has at least two glass transition temperatures, and a difference between the lowest glass transition temperature and the highest glass transition temperature is 30° C. or more, and in a cross section of the pressure sensitive adhesive particle, an area ratio of the island phases is 30% or more and 85% or less.
