PROBLEM TO BE SOLVED: To provide a vaporizing apparatus stably vaporizing a volatile chemical over a somewhat long period. SOLUTION: The vaporizing apparatus is composed of a chemical composition-containing carrier and a fan. The chemical composition-containing carrier is arranged in an air stream produced with the fan. The chemical composition-containing carrier is obtained by mixing the volatile chemical with an embedding material so as to provide 0.1-50 ratio of the embedding material/ volatile chemical expressed in terms of weight ratio and supporting the resultant mixture on a granular carrier having 1-15 mm grain diameter.
