Further, for example, the conducting wire connected to the electrode 21 can be taken out from below the top plate 2 through the through hole 22A and connected to the outside. This improves the appearance of the desk device 1 as compared with a configuration in which the electrode connecting portion 30 is provided outside the base material 22, for example, when electrically connecting to a device that is driven according to the operation of the user. At the same time, the desk device 1 can be made into a compact configuration.
Further, since the support 5 has an elevating mechanism, the top plate 2 can be elevated and lowered.

Further, since the electrode 21 is arranged between the decorative material 20 and the base material 22, the distance between the electrode 21 and the finger of the user who operates on the top plate 2 can be shortened. Therefore, when the user's finger comes into contact with the electrode 21, the change in capacitance can be easily detected.
Further, since the electrode 21 is printed on the sensor sheet 23, the shape of the electrode 21 can be freely changed, and the shape of the electrode 21 can be freely changed. It becomes possible to produce, and the initial cost for manufacturing can be suppressed.

Further, a through hole 22A is formed in the base material 22, and at least a part of the electrode 21 is arranged so as to face the through hole 22A. Therefore, it is possible to increase the size of the electrode 21 in the top view while reducing the size of the through hole 22A in which the electrode connecting portion 30 is arranged in the top view. As a result, the through hole 22A can be made smaller to secure the strength of the top plate 2, and the electrode 21 can be made larger to widen the range on the top plate 2 that the user can operate.
