POROUS STRUCTURE AND METHOD FOR PRODUCING SAME

A functional material having excellent photocatalytic activity, electric characteristics and the like is provided. A porous structure body 10 comprises a first target material 20 and an aggregate body 30 formed by aggregation of the first material. The aggregate body 30 adheres to the first target material and is located so as to surround the first target material. The aggregate body has a plurality of first pores 32 unevenly distributed near the first target material in the aggregate body and a plurality of second pores 34 scattered over the aggregate body.
