A vibrator element includes a substrate that performs thickness-shear vibration, wherein an outer shape of the substrate in a plan view has a first side and a second side arranged in a first direction along a direction of the thickness-shear vibration and extending along a second direction crossing the first direction, a third side and a fourth side arranged in the second direction and extending in the first direction, a first connecting portion connecting the first side and the third side, and a second connecting portion connecting the first side and the fourth side, the first connecting portion and the second connecting portion are located inside of a region surrounded by the first side, the second side, the third side, the fourth side, and extension lines of these sides in the plan view, and the substrate has broken-off portions projecting from the first connecting portion and the second connecting portion.
