In the figure, reference numeral 10 denotes a shelf, and this shelf 10 is fixed in a hollow inside of the wall panel 20 so as to be embedded therein. For example, the shelf 10 is placed facing the washroom of a wall panel 20 used between the washroom and the bath unit.

That is, generally, although not shown, a heat insulating material and a soundproof material are housed in the hollow inside of the wall panel 20. However, since the wall panel 20 used between the washroom and the bath unit does not need heat insulation and sound insulation, the heat insulation material and the sound insulation material wall are not stored, and the wall panel 2
0 was used as it was hollow. On the other hand, in the washroom, a relatively large amount of small items used for washroom, hairdressing, or bath are stored. Conventionally, these small items have been stored by providing a hanging shelf or the like on the wall. However, when a hanging shelf or the like is installed, the hanging shelf or the like projects from the wall panel 20 toward the room side, and thus there is an adverse effect that the washroom becomes narrower by that amount.

In view of this, in this embodiment, the shelf 10 is fixed to the inside of the hollow of the wall panel 20 facing the washroom, for example. Of course, as long as the room requires the shelf 10, it can be used not only in the washroom. First,
The structure of the above wall panel 20 will be described with reference to FIGS. 1 and 2 . As shown in FIGS . 1 and 2 , the wall panel 20 includes a rectangular frame-shaped outer frame 21 and an outer frame 21.
