摘要： A white key of a keyboard instrument includes: an upper wall elongated in a front and rear direction; and a pair of side walls extending downward respectively from right and left edges of the upper wall and each elongated in the front and rear direction. The upper wall and the pair of side walls define an inner space opening downward. The upper wall and the pair of side walls include: a narrow portion and a wide portion wider in a right and left direction. The white key has right and left portions with respect to a center line of the narrow portion. The right and left portions are different in construction to adjust a balance of load between the right and left portions with respect to the center line.
