To provide a contact plate and a switch apparatus using the same, in which a protrusion is easily formed on a contact plate, and a good operation feeling is provided at pressurizing even if dislocation exists relative to a keytop.

There are provided an elastic thin plate 1h comprising an invertible swollen part 1c, a through hole 1d that penetrates the top of the swollen part in inverting direction, and a protruding member 2 which is held in the through hole 1d, with its coming off being prevented, while one end protrudes in the swelling direction of the swollen part. A pressurizing part 2a is so formed as to transmit the pressurizing force from outside at one end of the protruding member 2.
