A vibrating piece substrate includes: a plurality of tuning-fork vibrating pieces each having a base portion, and vibration arm portions and support arm portions extending from the base portion; a frame portion; and a plurality of linking portions connecting the frame portion and the plurality of tuning-fork vibrating pieces, wherein the support arm portions extend in the same direction as the direction in which the vibration arm portions extend, and the support arm portions have a length smaller than the vibration arm portions, the tuning-fork vibrating pieces are arranged such that the vibration arm portions of adjacent tuning-fork vibrating pieces sandwich the region of a portion of the frame portion therebetween, measurement pads are formed in the region of the frame portion sandwiched between the vibration arm portions, and wiring lines are formed in the linking portions to provide electric conduction between the tuning-fork vibrating pieces and the measurement pads.
