Abstract
A keyboard apparatus that can be manufactured with a simple process at a low cost while still providing the feeling and appearance of high quality. In one embodiment of the invention, side surfaces of the white keys in the keyboard apparatus comprises a grained portion with a wood grain pattern. In this embodiment, when a white key is pressed down, the grained portion is visible from the side to give the appearance that the white keys are made from wood with a layer of white resin on the top and front surface. In another embodiment of the invention, a lower surface of a front end portion of the white keys is packed with a material such as resin. With this embodiment, when a performer's fingernail hits the top surface of the white keys while using the keyboard apparatus, the production of an unpleasant sound can be avoided.
