A vibrating device includes a dust-screening member shaped like a plate as a whole, a vibrating member arranged outside the dust-screening member and configured to produce, at the dust-screening member, vibration having a vibrational amplitude perpendicular to a surface of the dust-screening member, a counter member spaced apart from that surface of the dust-screening member, on which the vibrating member is arranged, a pushing member configured to push the dust-screening member onto the counter member, and a first support member arranged between the counter member and the dust-screening member, surrounding a center of the dust-screening member, and configured to support the dust-screening member when pushed by the pushing member. The first support member is pushed with a pressure of 2 N or less when the pushing member pushes the first support member.
