a multiplicity of key substrates extending in a front-to-rear direction of a keyboard, said multiplicity of key substrates being juxtaposed with a difference of semitone;

a plurality of key top mounting portions provided in the front-to-rear direction on each of said key substrates; and

a key top mounted on a key top mounting portion to thereby configure said keyboard.
