The net 15 is fixed to the grid portion 16 and the filter frame 20 by solidifying.

When the resin flows into the lattice portion 16, the speed at which the resin flows decreases while the resin flows from the first portion 31 to the second portion 32. When the flow of the resin at the first site 31 is high enough to cause breakage in the net 15, the speed at which the resin flows at the second site 32 can be reduced, so that the rate at the second site 32 can be reduced. Breakage of the net 15 can be reduced. The filter portion 10 can strengthen the fixation of the net 15 in the grid portion 16 by reducing the breakage of the net 15 at the second portion 32. Further, the filter unit 10 can reduce the breakage of the net 15 caused by the breakage of the net 15 in the grid portion 16 extending to the outside of the grid portion 16. The filter unit 10 can reduce the breakage of the net 15 caused by the breakage in the first portion 31 spreading to the outside of the grid portion 16 even when the breakage of the net 15 occurs in the first portion 31.

In the filter unit 10, when the filter frame 20 is provided with the third portion 33, the width of the fixed portion between the net 15 and the filter frame 20 is widened, so that an external force is applied to the net 15. It is possible to reduce the breakage of the net 15 in. Further, similarly to the second portion 32, the speed at which the resin flows can be reduced in the third portion 33 as well. The filter unit 10 can reduce the breakage of the net 15 at the third portion 33. The filter unit 10 can strengthen the fixing of the net 15 in the filter frame 20 by reducing the breakage of the net 15 at the third portion 33. Further, the filter unit 10 can reduce the breakage of the net 15 caused by the breakage of the net 15 in the filter frame 20 extending to the outside of the filter frame 20.

The cross-sectional shape of the vertical line portion 23 and the horizontal line portion 24 may be different from the cross-sectional shape shown in FIG. In the first portion 31, the size of the protrusion on the upper side and the lower side of the net 15 may be the same. The second portion 32 may be provided only on one of the upper side and the lower side of the net 15. Even when the second portion 32 is provided on one of the upper side and the lower side of the net 15, the filter unit 10 can obtain the effect of reducing the breakage of the net 15.

According to the first embodiment, in the bathroom dryer 100, the second portion 32 protruding from the first portion 31 along the net 15 is provided in the filter portion 10, so that the net 15 in the filter portion 10 is broken. It has the effect of being able to be reduced.
