However, in the vicinity of the membrane sheet 36 on the operation surface or the display surface 35, there are a plurality of convex shapes 37 protruding from this surface,
Since the high temperature frying pan does not directly touch the membrane sheet 36, deformation and discoloration are less likely to occur. In fact, if the gap is at least about 1 mm, deformation can be prevented with PET film. By doing so, even if the frying pan having a high temperature accidentally covers the membrane sheet 36 on the operation surface or the display surface 35, it is possible to provide a highly safe device without deformation or discoloration.

Even when the plate 32 adhered on the upper case 31 is round, there is a convex shape 37 between the plate 32 and the membrane sheet 36 on the operation surface or the display surface 35 at the left and right positions. Then, the same effect can be obtained.
