Abstract:
A vibrator element includes: a base section formed on a plane including a first direction and a second direction perpendicular to the first direction; and a vibrating arm extending from the base section in the first direction, wherein the vibrating arm flexurally vibrates in a normal direction of the plane, and has a first surface one of compressed and extended due to the flexural vibration and a second surface one of extended when the first surface is compressed and compressed when the first surface is extended, the first surface is provided with a first mass section, and the second surface is provided with a second mass section, and at least one of the first mass section and the second mass section has a portion, which fails to be opposed to the other of the first mass section and the second mass section in a plan view in the normal direction.
