A resonator that includes a rectangular vibrating portion having first and second pairs of sides that provides contour vibration. A frame surrounds a periphery of the vibrating portion and a first holding unit between the frame and one of the first sides and includes a first arm substantially in parallel to the vibrating portion, multiple second arms connecting the first arm with the vibrating portion, and a third arm connecting the first arm with the frame. A first connection line is on the first arm; a first terminal is on the frame; three or more electrodes are on the vibrating portion; and multiple first extended lines are on the second arms and connect first and second electrodes with the first connection line. The first extended lines are connected to the first connection line, which is electrically connected to the first terminal.
