The present invention relates to a first base polymer (A) made of at least one kind of thermoplastic polymer and a second base polymer made of at least one kind of thermoplastic polymer and not miscible with the first base polymer (A). (B), neither of the first base polymer (A) nor the second base polymer (B) are miscible, and the thermal decomposition point of the first base polymer (A) and the second Among the thermal decomposition points of the base polymer (B), the additive (C) comprising at least one kind of substance in a liquid or slurry state at the lower thermal decomposition point, (A), (B) and (C) It is a polymer composition which phase-separates and the two-phase interface which contact | connects each forms the three-dimensional continuous parallel interface. |
