OZONE GAS DETECTING ELEMENT

摘要

This invention provides an ozone gas detecting element (102) comprising a porous body (121), which is porous glass with a plurality of micropores (122) having an average pore diameter of 4 µm, a detecting agent (123) provided within the pore (122), and a selective transmission film (124) which is formed of a plastic film and is provided so as to cover the surface of the porous body (121). The selective transmission film (124) is formed of, for example, an organic polymer prepared using, as a monomer, a compound of a vinyl-containing chain molecule, such as polyacrylonitrile or PMMA and has a thickness of about 0.05 µm to 1 µm.
