That is, the porous regions 200 of the 2a to 2c regions may have different pore diameters. With the structure as described above, as the porous region 200 having a three-layer structure having different pore diameters is formed, the scent transmitted from the scent-repellent material can be better transmitted to the user. For example, as the diameter of the pores of the porous region 200 increases from the 2a region 210 to the 2c region 230, the size of the pores in the porous region 200 may be increased. Since the diameter of the pores is large, the user has the effect of being able to feel the scent transmitted from the scented material. However, it is not limited to the above example regarding the diameter of the pores, and may be formed such that the diameter of the pores becomes smaller as it goes toward the center of the dish, that is, from the 2a region to the 2c region, as well as sequentially increasing as described above. It is natural that they can be formed in different diameters without being smaller or smaller.
