To provide a metal dome sheet 10 to which a metal dome 8 is attached. The metal dome 8 elastically deforms with a pressing operation of a key top 16, thereby to have electrical conduction with a contact 6 provided on a substrate 2, and restores from a deformed state when the pressing operation is released, thereby to release the conduction with the contact. The metal dome sheet 10 has an elastic pressing projection 12 which transmits pressing force applied from the key top 16 side to a top 8a of the metal dome 8.
