Abstract
A quartz vibration element that includes: a quartz plate having first and second principal surfaces; first and second driving electrodes on the first and second principal surfaces, respectively, wherein when an X-axis, a Y-axis, and a Z-axis are defined as crystallographic axes of a quartz crystal of the quartz plate, an X'-axis and a Y′-axis are obtained by rotating the X-axis and the Y-axis about the Z-axis by a rotation angle φ, and a Y″-axis and a Z′-axis are obtained by rotating the Y′-axis and the Z-axis about the X′-axis by a rotation angle θ, the first and second principal surfaces are perpendicular to the Y″-axis, and when one of the first or second principal surfaces is viewed in plan and an angle ψ is between the X-axis and a long side of the quartz plate, the quartz plate satisfies both Ψ=α×φ×θ and −0.0165−0.016≤α≤−0.0165+0.016 or +0.0165−0.016≤α≤+0.0165+0.016.
