The present invention provides a vibration element with excellent vibration characteristics capable of preventing the vibration from leaking, a vibrator including the vibration element, an oscillator, and an electronic device. The vibration element (200) includes: a base unit (220); a pair of vibration arms (230, 240) which protrude in the +Y direction from the base unit and are arranged in parallel with an interval in the X-axis direction crossing the Y-axis direction on a plane; and a support arm (250) which protrudes in the +Y direction from the base unit. The base unit is placed on the opposite side to the side where the support arm protrudes while taking the center of the base unit as a boundary. The base unit also has a first axis width unit (222) of which the length in the X-axis direction gets shorter as getting further from the support arm within the range of the interval on a plane. |
