  • Patent number: 11425834
    Abstract: An information device and a cover that are suitable for forming design marks on a soft material and enhance the appearance quality. The cover includes: a core as a base; an auxiliary sheet closer to a surface than the core; a surface material closer to the surface than the auxiliary sheet, the surface material being softer than the core; and a design mark part including a baseplate and a design mark protruding from the baseplate. The baseplate is disposed in a plate recessed portion having a shape corresponding to a contour of the baseplate and disposed in a surface of the core. The design mark is exposed to the surface through design mark holes in the auxiliary sheet and the surface material, the design mark holes having a contour shape of the design mark. The auxiliary sheet covers at least the contour of the baseplate and the plate recessed portion.
