1. A porous structure having pores communicating with each other, comprising:
a porous structure portion A comprising a resin A; and
a porous structure portion B comprising a resin B,
wherein the porous structure portion A and the porous structure portion B are continuously integrated via a resin having a chemical structure gradually changing from a chemical structure similar to the resin A to chemical structure similar to the resin B,
wherein the resin A and the resin B are composed of different constituents,
wherein at least one of the resin A and the resin B includes an intramolecular cross-linked structure, and,
wherein the resin A has a glass transition temperature or melting point of 160 degrees C. or higher and the resin B has a glass transition temperature or melting point of lower than 160 degrees C.,
wherein the resin A comprises an acrylate resin, methacrylate resin, urethane acrylate resin, or vinyl ester resin, and
wherein the resin B comprises an acrylate resin, methacrylate resin, urethane acrylate resin, or vinyl ester resin.
