Abstract
A vibration plate for a musical instrument includes: a plate-shaped vibration plate main body that has a deformation anisotropy property; a first elongated reinforcing member disposed on a first face of the vibration plate main body, and that projects outwardly from the first face and extends along the first face in a direction that prevents the vibration plate main body from deforming; and a second elongated reinforcing member disposed on a second face of the vibration plate main body, and that projects outwardly from the second face and extends along the second face in the direction that prevents the vibration plate main body from deforming. As viewed from a thickness direction of the vibration plate main body, at least part of the first elongated reinforcing member overlaps with at least part of the second elongated reinforcing member.
