A decorative molding body, a push button switch keytop, and a push button switch key sheet are provided to enhance the external beauty of the push button switch by forming a decorative member on a bottom of a transparent member. A key sheet(10) includes a keytop(12) and a base sheet(11), which is made of a silicon rubber or a thermoplastic elastomer. A pattern printing layer, a luminance layer, and a coloring layer are sequentially laminated on a bottom of a keytop main body. The transparent printing layer and the luminance layer form a 3D bottom pattern layer. A display layer, which represents characters and symbols, is formed on the coloring layer. A decorative layer is formed on the bottom of the keytop. A visual ray is effectively irradiated on the decorative layer. |
