摘要： A sustained release body includes: a substrate containing a vaporizable active ingredient, the substrate having a structure for releasing a vaporized gas of the active ingredient; and a vapor deposition polymerization film directly formed on a first surface that is one end surface of both end surfaces of the substrate in a thickness direction of the substrate, the vapor deposition polymerization film being configured to receive the vaporized gas of the active ingredient from the first surface of the substrate and sustainedly release the vaporized gas.
