A structure (10) is provided with a barrier part (14) of a porous material for forming a plurality of cells (12) as flow paths for a mixed gas as a fluid, a functional layer (16) provided to an inner surface (15) of the barrier part (14), a protective layer (18) provided to an inner surface end part (15a) of the inner surface (15), and a seal part (19) provided to an end face (17) of the barrier part (14). The functional layer (16) is provided to the inner surface (15) of the barrier part (14), includes metal ions, and the properties thereof are changed by light. The protective layer (18) is provided to the inner surface end part (15a) of the barrier part (14), and the length (B) (mm) from an end face (11) of the structure (10) with respect to the maximum length (A) (mm) of an opening of the cells (12) satisfies the relationship B/A ≥ 0.4. |
