[Problem] To provide a piezoelectric component which suppresses ripples in an oscillation frequency region, and achieves a stable oscillation frequency. [Solution] This piezoelectric component includes: a supporting substrate (1); a long piezoelectric element (2) having oscillation electrodes (21) on one main surface and the other main surface such that the main surfaces face each other; a first supporting section (31) and a second supporting section (32), which are provided between the supporting substrate (1) and both piezoelectric element (2) end sections in the long axis direction of the piezoelectric element; and a conductive bonding material (4) that bonds both the piezoelectric element (2) end sections, and the first supporting section (31) and the second supporting section (32) to each other. In a planar view, a center point (C2) of the piezoelectric element (2) is deviated from a middle point (C1) between the first supporting section (31) and the second supporting section (32).
