Patent attributes
A key having a key-depression surface with a woody characteristic and durability without the need of a surface treatment and capable of being formed from a simple-shaped uncompressed wood. A key for use as a black key includes a resin part and a compressed wood part secured at its lower surface to an upper surface of the resin part. The compressed wood part is used to constitute a portion of a key top including an upper surface and positioned above an upper surface of white keys which are in a non-key-depression state. The compressed wood part is obtained by compression molding of unprocessed wood. The compressed density in the vertical direction in the compressed wood part is higher toward rearward from a front end of the compressed wood part.
