Exemplary embodiments provide a tuning-fork-type vibrating reed having satisfactory frequency-temperature characteristics in a broad temperature range, i.e. a tuning-fork-type vibrating reed exhibiting small changes in frequency over a broad temperature range is provided. The tuning-fork-type vibrating reed according to exemplary embodiments of the present invention includes a GaPO4 piezoelectric material and a pair of arms having the thickness in Z′-axis direction, the width in X-axis direction, and the length in Y′-axis direction. The X-axis, the Y′-axis, and the Z′-axis are defined by rotating around the X-axis among the crystal X-axis, Y-axis, and Z-axis of the GaPO4 by an angle between 7.7 degrees and 11.3 degrees measured clockwise as viewed from the origin looking in the positive X-axis direction.
