A piezoelectric component which suppress ripples in the range of oscillation frequency and achieves stabilization of oscillation frequency is provided. A piezoelectric component of the invention includes a support substrate (1); a piezoelectric element (2) having an elongated shape, comprising excitation electrodes (21) disposed on one principal surface and the other principal surface thereof, respectively, the excitation electrodes (21) facing each other; a first support portion (31) and a second support portion (32) which are disposed between both ends in a longitudinal direction of the piezoelectric element (2) and the support substrate (1); and an electrically conductive joining material (4) which joins the first support portion (31) and the second support portion (32) to the ends of the piezoelectric element (2), respectively. A center (C2) of the piezoelectric element (2) is offset with respect to an intermediate point (C1) between the first support portion (31) and the second support portion (32) as seen in a plan view of the piezoelectric component.
