<p>A piezoelectric vibrating part in which vibration transmitted from a piezoelectric vibrator to the substrate side can be suppressed. In a piezoelectric vibrating part (1), a piezoelectric vibrator (11) is held on a case substrate (2) by first and second electrically conductive holding members (9, 10). The electrically conductive holding member (10) is mounted on the case substrate (2) so as to be located near one end of the case substrate (2). A terminal electrode (4) connected to the electrically conductive holding member (10) is mounted on the case substrate (2) so as to be located near the other end of the case substrate (2). The electrically conductive holding member (10) and the terminal electrode (4) are electrically connected to each other by a routed electrode (8).</p>
