METHOD FOR MANUFACTURING POROUS BODY, POROUS BODY, AND STRUCTURE

摘要

Provided are a method for manufacturing a porous body, a porous body, and a structure, the method for manufacturing a porous body being capable of readily controlling pore diameter and porosity, and being capable of forming a porous body having a smaller pore diameter and higher porosity than a conventional porous body. The method for manufacturing a porous body comprises: a film formation step (S3) for forming a film composed of a composite powder, the film having a first layer composed of a material soluble in a predetermined solution and a second layer, which formed by coating at least a portion of the outer side of the first layer with a metal or alloy and which is less soluble in the solution than is the first layer; and a pore formation step (S4) for forming pores in the film by immersing the film in the solution to remove the material from the film.
