A vibration generator includes a housing, a vibrating body, and a leaf spring. The leaf spring includes a connection portion connected to the vibrating body at one longitudinal end of the leaf spring, an attachment portion attached to a circumferential wall portion at the other longitudinal end of the leaf spring and an intermediate portion formed between the connection portion and the attachment portion to extend around the vibrating body. The connection portion and the attachment portion are arranged along a direction intersecting a vibration direction of the vibrating body at the opposite sides of the vibrating body. The intermediate portion is arranged in an outside region around the vibrating body to extend across the vibration direction of the vibrating body.
