Porous structure and a manufacturing method thereof

Providing photocatalytic activity, excellent functional material such as electrical characteristics. The porous structure 10 includes a first target material 20, and applied to the target material of the first, is positioned so as to surround the periphery of the first target material, the first target material and a flocculated agglomerate 30, wherein the agglomerates, the first plurality of first unevenly distributed in the target material side of the air holes 32, and the aggregate plurality of second interspersed in the aggregate comprising pores 34.
