As described above, since the lower case 34 has the double wall structure, the heat insulating effect is high, and by removing the outer case 34b, the outer wall surface of the storage section 40 is exposed, so that the heating element can be easily incorporated. Note that the lower case need not be provided in the double wall structure.

[0010] The storage section 40 is provided with the wet tissue container 4.
1 is formed in such a size as to be able to store the wet tissue container 41. Since there are various sizes of wet tissue containers depending on each manufacturer of the wet tissue, the largest wet tissue container among those manufacturers The size of the storage section 40 is set according to the size of 41. The storage section 40 is made of PP, PE, PC, P
It is formed of a synthetic resin such as S, AS, or PVC.
