| description | To provide porous silica having improved characteristics, and a method for manufacturing the same.SOLUTION: Porous silica PS has first pores P1 having an average pore diameter of 100-1000 nm and second pores P2 having an average pore diameter of 0.5-3 nm. The functional material includes the porous silica. The method for manufacturing the porous silica, capable of manufacturing the porous silica by the hydrolysis of alkoxysilane comprises the steps of: (a) preparing a first liquid including a surfactant, alkoxysilane and water; (b) gelling the first liquid by dehydration condensation reaction by contacting the first liquid to a basic liquid; and (c) heating a gelled material obtained by gelling the first liquid. In the (a) step, when a stoichiometric ratio of alkoxysilane to water is alkoxysilane:water=1:n, n is 20 or less.SELECTED DRAWING: Figure 2
