Abstract: Provided are a decorative sheet which is enhanced in durability of an edge portion of a soft feel layer thereof and which is unlikely to suffer breakage, a method of manufacturing such a decorative sheet, a decorative molded body, and a decorative key sheet. A compressed portion formed by crushing a foam layer in a thickness direction is provided at a side surface of an edge portion of a decorative sheet with a soft touch feeling.

Abstract: Provided is a key sheet which has a soft touch feeling and in which elaborate and highly visible display portions can be provided. In a key sheet including: a translucent base sheet; and a soft-feel layer which is laminated on a front surface side of the base sheet, includes a plurality of display portions representing key types such as letters, numerals, and symbols, and has a soft touch feeling, the soft-feel layer includes a translucent skin layer having the soft touch feeling and decorative portions which are provided on a back surface of the skin layer and are visible through the skin layer. Further, light emitted from an inside of a device transmits through the base sheet so as to reach the decorative portions, and hence it is possible to obtain an illumination-type key sheet excellent in illumination property and of wider variety.

Abstract: Disclosed is a key sheet helping to solve problems caused by a rubber-like elastic material filling dividing grooves. A key sheet is provided with protrusions swelling from the back surface of an operation plate toward dividing grooves. The protrusions, which are formed by a film sheet formed of a thermoplastic resin, can prevent the problems when the rubber-like elastic material filling the dividing grooves are exposed, that is, separation or severance of the rubber-like elastic material. Further, nails or fingertips are not easily allowed to enter the dividing grooves of the operation plate. The protrusions in the grooves formed by the film sheet are not easily worn out through repeated depressing operation, thus realizing a thin and safe key sheet.

Abstract: To provide a decorative sheet having enhanced durability of an edge portion of a soft feel layer and is unlikely damaged, a manufacturing method for a decorative sheet, a decorative molded body, and a decorative key sheet, a decorative sheet with a soft touch feeling has a foamed layer having a side surface of an edge portion

Abstract: According to a method of producing a key top for a pushbutton switch of the present invention, a base layer made of an insulating resin that can be plated with metal, an electroless plating layer to be formed on the surface of the base layer, and a polymer coating layer, if required, are stacked on the surface of a key top body. Alternatively, an electroplating layer formed by electroplating is further formed on the electroless plating layer. Therefore, a plating layer can be directly and easily formed on the insulating resin, whereby a key top for a pushbutton switch having a sensation of metal and being rich in design is obtained.
