PROBLEM TO BE SOLVED: To provide an agent storage container from which a used gelatinous agent can be easily removed and to provide an agent volatilization device using the agent storage container.SOLUTION: An agent storage container 1 has an end surface part 10 on at least one end thereof, is used by being installed so that the end surface part 10 is perpendicular to the horizontal direction, and makes a gelatinous agent stored therein volatilized to the outside from the other end. On an inner surface of the end surface part 10, at least one support member 34, which protrudes from the inner surface and penetrates the gelatinous agent, is provided. The support member 34 has a plurality of protrusion pieces 35 which extends in the surface direction of the end surface part 10 so that one ends of the protrusion pieces are connected to each other and the other ends of them are spaced from each other. In at least two protrusion pieces 35 of the plurality of protrusion pieces 35, one side surface 35A of one of the two protrusion pieces and one side surface of the other of them are adjacent to each other to form a V-shape or L-shape, and have an angle part 35B between them.SELECTED DRAWING: Figure 2
