an element that comprises a filter and a frame, the filter being configured to filter a gas, the frame holding a periphery of the filter and having flexibility; and
a case that accommodates the element,
wherein the case comprises a first member and a second member that are configured to be coupled to each other with the element interposed between the first member and the second member,
wherein the first member comprises
a frame holder configured to hold a periphery of the frame of the element in a case where the first member is coupled to the second member, and
a temporary holder configured to perform temporary holding of the frame so that a part of the frame of the element is separated from the frame holder and the frame is curved in a case where the first member is not coupled to the second member, and
wherein the second member comprises a temporary-holding canceller configured to cancel the temporary holding of the frame by the temporary holder in a case where the second member is being coupled to the first member.
