PROBLEM TO BE SOLVED: To obtain a silicone rubber key pad having a design effect and automatic returning function by obtaining the pad integrated with a plastic sheet, transferring a transfer layer to the sheet surface of its button part, and forming a design on a surface of the button part. SOLUTION: The silicone rubber key pad 1 integrated with a plastic sheet 3 having adhesive properties is obtained by holding the sheet 3 in a temperature regulated mold, fully finning uncured silicone rubber composition in a cavity, and opening the mold after the composition 5 is cured. Then, a transfer layer is transferred to a surface of the sheet 3 of its button part by using a transfer material, thereby forming a design 2 on a surface of the button part. To color the sheet 3, a coloring layer 4 may be formed on an overall rear surface of the sheet 3. |
