摘要: There is provided a method for producing porous glass having high porosity and nanosized pores even at deeper portion in the glass. A includes steps of preparing body containing boron, subjecting to heat treatment phase separation, bringing phase-separated into contact with boron-containing solution boron concentration 5 140 ppm.
