PROBLEM TO BE SOLVED: To provide an installation structure of a light-emitting element in a keyboard device capable of reducing probability of occurrence of connection failure and of reducing cost more than before. SOLUTION: The installation structure 1 of the light-emitting element 6 in the keyboard device 101 has: a key top 21; a light-emitting element 6; and a membrane sheet 3. On the key top 21, a transmission part 21b to transmit light is equipped. At the membrane sheet 3, a pair of wiring sheets 3a, 3b in which a wiring 7a pattern and a contact 31 are formed, and a spacer sheet 3c deployed between a pair of wiring sheets 3a, 3b are laminated. The light-emitting element 6 is installed on a sheet 7 for light-emitting element installation, a hole 8 for light-emitting element installation to penetrate a sheet except the sheet at the highest part of the membrane sheet 3 and at least the lowest part and a base plate 4 is installed at a position corresponding to the transmission part 21b of the key top 21. In the hole 8 for light-emitting element installation, the light-emitting element 6 is arranged. COPYRIGHT: (C)2011,JPO&INPIT
