Abstract
A bubble generating device includes a vibration plate, a first cylindrical body, a spring portion, a second cylindrical body, and a piezoelectric element. The vibration plate includes openings, a first surface in contact with a liquid in a liquid tank, and a second surface in contact with a gas. The first cylindrical body has a first end portion supporting the vibration plate. The spring portion has a plate shape and supports a second portion of the first cylindrical body. The second cylindrical body has an end portion supporting the spring portion at a position outward of a position at which the first cylindrical body is supported. The piezoelectric element causes the spring portion to vibrate and is inward of a portion of a surface of the spring portion supported by the second cylindrical body.
