PROBLEM TO BE SOLVED: To provide an aerosol valve capable of making compression gas introduced into a container of an aerosol product from a compression gas introduction hole of a mounting cup melt into a content fluid in the container more easily than before.SOLUTION: An aerosol valve 30 includes: a mounting cup 31 provided with a hole 31a formed for introducing carbon dioxide gas 12; a stem 32 inserted in the hole 31a; and a pipe 36 soaking in a content fluid 11 in a container 20 of an aerosol product 10. A housing 40 of the aerosol valve 30 is provided with a content liquid hole 40a for circulating the content liquid 11 and a compression gas hole 40b for circulating carbon dioxide gas 12. The housing 40 includes a backflow prevention part 40c which allows circulation of carbon dioxide gas 12 from the stem 32 side to the inside of the pipe 36 through the compression gas hole 40b and prevents circulation of carbon dioxide gas 12 from the inside of the pipe 36 through the compression gas hole 40b to the stem 32 side. |
