摘要
A tone plate which makes it easy to reduce the entire length and width thereof, thus increasing the degree of freedom in design. The tone plate includes an antinode portion, front and rear ends, and first and second supporting holes which are located closer to the front and rear ends than to the antinode portion and at which a vibration node can be formed. There are provided first and second mass concentrating portions extending toward the front and rear ends from locations on a side close to the first and rear ends with respect to the supporting holes. First and second thinner portions are respectively provided between the antinode portion and the supporting holes. The tone plate vibrates to generate a musical tone of a specific tone pitch when struck with being supported at the supporting holes.
