The invention relates to a quartz crystal vibrating body and a manufacturing method. The quartz crystal vibrating body comprises a quartz crystal and metal films, the metal films are arranged on the upper surface and the lower surface of the quartz crystal, each metal film comprises an electrode surface and an electrode pin, the electrode surface comprises a main vibrating area and a non-main vibrating area, the main vibration area is an overlapped part formed by the electrode surface on the upper surface or the lower surface of the quartz crystal, the non-main vibration area is a part not formed by the electrode surface on the upper surface or the lower surface of the quartz crystal, the main vibration area is smaller than the electrode surface, the main vibration area is circular, and the half perimeter of the main vibration area and the non-main vibration area are combined into a whole. According to the invention, the secondary wave of the quartz crystal vibrator can be reduced, and the frequency stability
