摘要：
PROBLEM TO BE SOLVED: To provide a key pad excellent in durability, of which an electrode layer is not broken by repeated operation.
SOLUTION: The key pad has a transparent key top and an EL sheet having a light
emission part having an external shape almost similar to or smaller than that of a contact face of the key top, joined to the contact face. The light emission part is formed by
laminating at least a transparent electrode layer, a light emission body layer, a dielectric layer, and a back face electrode layer. At least the light emission body layer out of above layers has an external shape larger than that of the contact face.
