Abstract
A process for manufacturing a porous body, includes preparing a dispersion liquid having a dispersion medium with cellulose-based nanofibers that have an average fiber diameter from 1 to 100 nm and dispersed therein, attaching the dispersion liquid to a porous support having a plurality of pores that connect with one another, removing the dispersion liquid attached to a surface of the porous support excluding an inside of pores of the porous support, and subsequently drying the porous support including the dispersion liquid in the pores of the porous support to remove the dispersion medium.
