A keyboard device includes: a support member; and keys swingably supported by the support member. One of the support member and the key includes a guide groove guiding swinging of a key rear portion, and the other includes a guide shaft extending in a scale direction, inserted into the guide groove, and sliding along the guide groove when the key swings. The keys comprise white and black keys. When a point where a guide shaft center is positioned in a pre-key-pressed state is a starting point of the guide groove, a point where the guide shaft center is positioned in a state where the key is pressed to an ending edge position is an ending point of the guide groove, and a line connecting the starting and ending points is an angle of the guide groove, the angle of the guide groove differs between the white or black keys.
