PROBLEM TO BE SOLVED: To provide a container for a volatile agent capable of replacing it with a container filled with a new content by a simple operation.SOLUTION: The container 1 for the volatile agent includes: an inner case 2 filled with the volatile agent and an outer case 3 which holds detachably the inner case 2 inside, and volatilizes the volatile agent in the inner case 2 in a state that the inner case 2 is held. The outer case 3 has a peripheral wall 14 which forms an opening performing taking in and out the inner case 2, and surrounds the periphery of the inner case by leaving the inner case to form a storing space for the inner case therein. At least one arc-shaped elastic plate 17 which is integrally connected with the peripheral wall 14 to a projecting part facing the opening of the peripheral wall 14 through a hinge prevents the inner case 2 from being pulled out by inverting the peripheral wall 14 inward, and allows the mounting and takeout of the inner case 2 through the opening by inverting the peripheral wall 14 outward is provided.
