摘要：
To provide an optical member in which crystallization is suppressed and which has a porous glass layer on a base material.An optical member has a base material 1 and a porous glass layer 2 which is formed on the base material 1 and has a three-dimensional through pore, in which the existence ratio of crystals of 0.2 micrometer or more in the porous glass layer 2 is 1.0% or lower.
