Abstract: A piezoelectric vibration device capable of allowing a low profile and generating strong vibration, and a portable terminal using the same are provided. Disclosed are a piezoelectric vibration device at least including a support body (11); a vibration member (12) mounted to the support body (11) so as to vibrate; a vibration element (14) capable of being subjected to bending vibration; and a deformable first connecting member (13) interposed between a first surface that is a bending surface of the vibration element (14) and one main surface of the vibration member (12), and a portable terminal using the same. A piezoelectric vibration device capable of allowing a low profile and generating strong vibration, and a portable terminal can be obtained.
