Abstract: A pressure sensitive adhesive particle includes a pressure sensitive adhesive base particle that contains a styrene resin containing styrene and a vinyl monomer other than styrene as polymerization components, and a (meth)acrylate resin containing at least two (meth)acrylates as polymerization components, in which a mass ratio of the (meth)acrylates relative to a total of polymerization components of the (meth)acrylate resin is 90 mass % or more; and an external additive. The pressure sensitive adhesive particle has a surface having an arithmetic average roughness Ra within a range of 0.005 μm to 0.100 μm. The pressure sensitive adhesive particle has at least two glass transition temperatures, and the difference between the lowest glass transition temperature and the highest glass transition temperature among the glass transition temperatures of the pressure sensitive adhesive particle is 30° C. or more.
