Abstract: A powdery and/or granular material which achieves excellent dispersibility of fine polymer particles in a matrix resin is provided. The powdery and/or granular material contains specific fine polymer particles (A) and a specific resin (B), and has pores with an average pore diameter of 0.03 μm to 1.00 μm, where a total volume of the pores is not less than 0.0600 mL/g.
