PROBLEM TO BE SOLVED: To provide a crystal piece aggregate capable of maintaining the shape of crystal oscillating pieces without entering the etching in the principal surface, in the crystal piece aggregate in which the etching is applied to the crystal substrate and a plurality of the crystal oscillation pieces are formed. SOLUTION: The crystal piece aggregate having a principal surface where a crystal substrate is parallel to X axis and is inclined to Z axis, includes a support part 11 extended in a direction orthogonal to the X axis of the crystal substrate, a plurality of connecting parts 12 extended from the support part 11 in the direction parallel to X axis, and a rectangular crystal piece part 13 connected to the end of the connecting parts 12 and extended in the direction parallel to X axis. One crystal piece part 13 is connected to two connecting parts 12. The external surfaces 14 of the connecting parts 12 are continuously formed along the side faces 15 of the crystal piece part 13.
