A flexural vibration piece including a vibrator having a first region on which a compressive stress or a tensile stress acts and a second region on which a tensile stress acts when a compressive stress acts on the first region and a compressive stress acts when a tensile stress acts on the first region, and performs flexural vibration in a first plane; and a heat conduction path formed of a material having a thermal conductivity higher than the vibrator and that thermally connects the regions, wherein when m is the number of heat conduction paths, &rgr;th is the thermal resistivity of the heat conduction path, &rgr;v is the thermal resistivity of the vibrator, tv is the thickness of the vibrator in a direction orthogonal to the first plane, and tth is the thickness of the heat conduction path, a relationship of tth≧(1/m)×tv×(&rgr;th/&rgr;v) is satisfied.
