A double rotation Y-cut crystal unit includes a crystal element, which is respectively rotated by an angle [theta] DEG and an angle [phi] DEG in a counterclockwise direction centering on an X axis and a Z axis of crystal axes (X, Y, Z), which principal surface is perpendicular to a Y'' axis of newly-generated rotated crystal axes (X', Y'', Z'), and which is formed into a rectangular geometry longer in one direction, wherein a direction of the long side of the crystal element corresponds to a rotated X' axis direction when the X' axis is rotated by an angle [alpha] DEG in the counterclockwise direction with the X' axis serving as a central axis in a plane of X'-Z' of the rotated crystal axes serving as the principal surface, and wherein the angle [alpha] DEG is set to (30-[phi]) DEG +45 DEG .
