Abstract
A keyboard instrument includes a plurality of key blocks, each including key main bodies, connecting sections, and a supporting section. Each key main body has a top surface that can be pressed by a user to play the keyboard instrument. Each connecting section extends from a key main body and deforms in response to pressing at the top surface of the key main body. The supporting section supports the key main bodies as one key block through the connecting sections. The key blocks are stacked at the supporting section in an instrument case so that a plurality of connecting sections of one key block and a plurality of connecting sections of another key block overlap each other. In at least one key block, each connecting section extends from a top surface side of the corresponding key main body.
