Abstract:
A resonator element satisfies, when a shortest distance between a first end portion and a second end portion of a base is Wb [m], an effective width of the base in a Y axis direction is We [m], and a Q value of the resonator element is Q, the following expressions (A) and (B). Q={(ρ·Cp)/(c·α2·Θ)}×[{1+(2·ρ·Cp·We2·f/(π·k))2}/(2·ρ·Cp·We2·f/(π·k))] (A) 0.81≦Wb/We≦1.70 (B)
