<p>A low-profile vibration device capable of generation of great vibration and a portable terminal employing the vibration device. The vibration device includes: a support body; a vibration member supported so that its periphery is connected to the support body, the vibration member having a first portion which is connected to the support body, and a second portion which is located inside the first portion and is not connected to the support body; and a vibration element whose one surface in a first direction is connected to one main surface of the second portion in the vibration member, bending vibration of the vibration element in the first direction whose amplitudes vary along a second direction perpendicular to the first direction being caused by electrical signal input.</p> |
