PROBLEM TO BE SOLVED: To enable buttons to operate independently of one another by forming a cut in the key pad, having a button parts formed of projection parts at its base part, along the border between the button part and base part. SOLUTION: The key pad 1 having the button part 5 formed of the projection parts at the base part 6 has the cut 7 formed along the border between the button part 5 and base part 6. For example, a transparent or translucent plastic sheet 2 having a pattern layer 3 is formed in a projection shape at the button part 5 and resin is charged in the plastic sheet 2 on the reverse surface of the button part 5. Or a projection part made of transparent resin is adhered onto the transparent or translucent plastic sheet 2 having the pattern layer 3. The cut 7 is formed to >=50% of the border between the button part 5 and base part 6. When the cut 7 is <50%, buttons which are close to each other move interlocking when one button is pressed. |
